Stop thinking in ingredients. Think in jobs.

Here's why most advice on this topic is useless. It tells you what vegans don't eat, hands you a substitution chart, and sends you off. Then your cake comes out of the oven like a paving slab and the chart doesn't explain why.

The chart failed because it was matching ingredients to ingredients. Butter goes to margarine. Milk goes to oat milk. Egg goes to… flax egg, apparently, in every recipe, regardless of what the egg was there for.

But an egg in a meringue and an egg in a meatball are doing completely unrelated things. One is a protein scaffold holding air. The other is glue. A flax egg is a decent glue and a hopeless scaffold, which is why the same substitution triumphs in one recipe and collapses in the next.

So the useful question isn't what replaces eggs. It's what was this egg doing here — and then you pick the replacement that does that job.

Once that clicks, vegan cooking stops being a minefield of arbitrary rules and becomes something closer to normal cooking with a slightly different toolkit. Vegetarian cooking, by contrast, keeps the whole original toolkit. That's the real gap between the two, and it's a technical gap, not a moral or nutritional one.

What an egg was actually doing

Eggs are the most overqualified ingredient in your fridge. They hold five or six distinct roles, and no single vegan substitute covers more than two.

A few of these deserve more than a line.

Aquafaba is the strangest and best discovery in modern vegan cooking. It's the cloudy liquid in a tin of chickpeas — the stuff everyone poured down the sink until around 2015, when cooks worked out that its dissolved proteins and starches whip into a foam that behaves remarkably like egg white. Stiff peaks. Meringue. Mousse. Three tablespoons stands in for one whole egg, two for a white. It sounds like a party trick and it genuinely isn't.

Flax and chia "eggs" — a tablespoon of ground seed in three of water, left to gel — are excellent binders and nothing else. Brilliant in burgers, muffins, cookies. Useless anywhere you needed lift.

The practical upshot: read the recipe and ask what would go wrong if you simply left the egg out. If it would fall apart, you need a binder. If it would be flat, you need aeration. If it would split, you need an emulsifier. Then choose accordingly.

What dairy was actually doing

Dairy is subtler than eggs, which makes its absence harder to diagnose. Four jobs, roughly.

Fat, and what fat carries. A lot of flavour compounds are fat-soluble, which is why butter tastes of more than fat. Plant fats replace the richness readily enough — olive oil, coconut, cashew cream, good vegan butter — though each brings its own flavour to the party rather than staying politely neutral. Coconut in particular does not stay neutral.

Browning. This one catches people out. Milk contains both protein and lactose, and that combination drives the Maillard reaction — the browning that gives baked goods their colour and roasted depth. Take the dairy out and things come out paler and taste flatter, even when the texture is fine. A little maple syrup or plant milk with some protein in it (soy browns better than most) helps close the gap.

Acidity and culture. Buttermilk, yogurt and soured cream do chemical work: reacting with raising agents, tenderising, cutting richness. Plant milk plus a spoon of lemon juice or vinegar reproduces the acidity well. Cultured plant yogurts have improved enormously.

Cheese. Its own section, below, because it deserves one.

For depth of savoury flavour — the thing people usually mean when they say vegan food tastes "flat" — the fix isn't a dairy substitute at all. It's glutamates. Nutritional yeast, miso, dried mushrooms, tomato paste caramelised until it darkens, soy sauce, roasted alliums. Build umami from those and the dairy isn't missed.

The first thing that goes wrong is almost never the substitute you chose. It's that nobody asked what the ingredient was doing there in the first place.

Which is worth sitting with for a second, because it explains the most frustrating failures. Someone swaps butter for oil in a shortcrust pastry and gets something crumbly and greasy — not because oil is bad, but because butter was contributing water and solid fat structure, and oil contributes neither. Someone replaces milk with water in a bread dough and wonders why the crust stays pale, when it was the milk proteins and lactose driving that colour. In both cases the substitute was reasonable. The diagnosis was missing.

Easy, hard, and genuinely difficult

Not all cooking converts equally, and anyone who tells you it does is selling something. Roughly:

Savoury cooking converts easily because most of it was never leaning on dairy or eggs for structure. A lentil dal, a tomato sauce, a Thai curry built on coconut milk — swap the ghee for oil where it appears and you're largely done.

Baking is where the technique lives. Cakes and pastry rely on eggs for structure and dairy for tenderness and browning, so you're rebuilding the chemistry rather than swapping a component. It's absolutely doable — vegan baking is a well-developed craft — but expect to follow recipes designed as vegan rather than converting your grandmother's. Our dessert classes cover this properly, and the same rebuild-the-chemistry logic applies to gluten-free baking, which is why the two often get taught together.

Cheese is the honest limit. Aged cheese flavour comes from months of enzymatic breakdown, and the stretch of melted mozzarella comes from casein, a milk protein that behaves in a way plant proteins simply don't replicate. Modern vegan cheeses have improved enormously — cultured cashew versions are genuinely good — and they still aren't cheese. That's fine. The trick is to stop asking them to be, and to cook dishes where a cashew cream or a savoury sauce does the job cheese was doing, rather than dropping in a substitute and being disappointed.

Side by side

That last row matters more than it looks. Plenty of things read vegetarian and aren't — traditional Parmesan uses animal rennet, marshmallows use gelatine, Worcestershire and many Thai and Vietnamese dishes use fish sauce. And plenty read vegan and aren't: honey, ghee, and whey or casein hiding in the ingredients list of things that otherwise look plant-based.

The cuisines that were vegan all along

This is the part that reframes the whole subject, and it's the bit most Western-centric articles miss entirely.

Vegan cooking is not a modern invention requiring a shelf of specialist products. Enormous parts of the world's culinary heritage are plant-based by tradition — not as a substitute for anything, just as how people have eaten for centuries.

• Ethiopian cooking has an established tradition of fasting days on which no animal products are eaten at all. Misir wot, shiro, gomen, the whole spread on injera.
• South Indian cooking gives you sambar, rasam, coconut chutneys, dosas — a vast repertoire that never needed dairy in the first place.
• Southeast Asian curries built on coconut milk rather than cream. Richness without a cow in sight.
• Levantine and North African cooking — hummus, ful medames, tabbouleh, chickpea and vegetable tagines — is heavily plant-based by default.

Now the flip side, which trips people up constantly: a great many celebrated vegetarian cuisines are emphatically not vegan. North Indian vegetarian cooking runs on ghee, paneer and yogurt. Italian vegetarian cooking is built on cheese and eggs. Assuming "vegetarian restaurant" means "vegan-friendly" is a mistake people make once.

The practical takeaway is a good one: rather than veganising a dish that fights you, cook a dish that was already there. It's more interesting food, and you skip the substitution problem entirely. P2Bridge hosts come from more than 20 countries, and several teach dishes from precisely these traditions — worth browsing the cultural experiences alongside the cooking categories.

Cooking for a mixed household

Most people reading this aren't cooking for a table where everyone eats the same way. One vegan, one vegetarian, someone who eats everything, possibly a teenager going through a phase.

The strategy that works: cook a vegan base and let people add. A curry, a grain bowl, a tomato-based pasta sauce, a tray of roasted vegetables — all naturally vegan — then put the cheese, the yogurt, the fried egg, the meat on the table as additions rather than cooking three dinners.

It's less work, not more. And it avoids the trap of treating the vegan as someone who gets a sad separate plate while everyone else eats the real meal.

One caution worth naming: if you're cooking for someone with an allergy rather than a preference — dairy allergy is a different thing from choosing not to eat dairy — cross-contamination genuinely matters. Separate utensils, clean surfaces, and ask rather than assume.

Where people go wrong

Substituting without asking what the ingredient was for

Covered above, and it's the root of most failures. One "egg replacer" for every job is how you get a flat cake.

Under-seasoning, then blaming the plants

Dairy and meat bring salt, fat and glutamates along for free. Remove them and you have to add that depth deliberately — salt, acid, umami, and enough fat. Vegan food tasting bland is nearly always a seasoning problem wearing a costume.

Building meals around a single "meat substitute"

A block of plain tofu in the middle of the plate, doing the job a chicken breast used to do, is a joyless way to eat. The cuisines that do this best don't centre a protein at all — they layer legumes, grains, vegetables and sauce into something that doesn't have a hole in the middle.

Treating tofu badly

Press it. Season it properly. Get real colour on it. Tofu straight from the packet into a pan is how tofu got its reputation, and it's entirely undeserved.

Nutrition, briefly and honestly

Learning this properly

Vegan and vegetarian cooking are unusually well suited to being taught live, and the reason is specific rather than promotional.

The moments that go wrong are moments of judgement, not instruction. Whether your aquafaba has reached stiff peaks or is about to collapse. Whether the batter looks right before it goes in the oven — which, for a vegan cake, looks noticeably different from a conventional one, and a recipe photo won't tell you that. Whether that sauce is about to split. Whether the tofu is actually browning or just sitting there.

Those are all things a teacher watching your pan can call in the moment, and all things a recipe card and a video are structurally incapable of doing. It's why every class on P2Bridge is live rather than recorded.

The other advantage is more interesting. If you want to learn the vegan dishes of a tradition that has been cooking them for centuries, the best teacher isn't necessarily nearby — they're wherever they are. Learning South Indian or Ethiopian or Levantine cooking from someone who grew up eating it is a different experience from learning a Westernised approximation, and geography stops being the limit.
