Why the swap works
Gelatin's trick is a thermo-reversible protein gel: it melts in the mouth and sets softly. Plant hydrocolloids gel by different chemistry, so each matches a different part of gelatin's behaviour. Agar (from red algae) sets firmly at room temperature and stays set when warm — ideal for terrines and firm jellies, though it lacks gelatin's melt. Pectin (from citrus and apple) gives the soft, short set of jam and fruit gummies. Iota carrageenan makes elastic, dairy-style gels; kappa sets firmer and lambda only thickens. Konjac needs a suitable gum blend or alkaline treatment for a firm, chewy gel. The practical rule: use agar where you want a clean, firm set; pectin for soft fruit textures; and a blend of starches and carrageenan — or a commercial 'vegan gelatine' — where you want the closest match to gelatin's wobble.
Options, ratios and best uses
Agar agar
1 tsp powder per 250 mlMust boil 2 minutes to activate; sets at room temperature.
Best for: jelly, panna cotta, terrines
Pectin
per packHigh-methoxyl pectin needs sugar and acid; low-methoxyl types use calcium.
Best for: jams, pâte de fruit
Carrageenan
0.5-1%Iota gives elastic gels; kappa sets firmer, while lambda only thickens.
Best for: soft dairy-style desserts
Konjac / glucomannan
Per tested recipe or blend instructionsNeeds a suitable gum blend or alkaline treatment to form a firm gel.
Best for: chewy sweets

Tips
- Follow the agar packet or a tested agar recipe for the desired firmness
- Test a spoonful on a cold plate
- Acidic juices weaken agar — add a little more
Avoid
- Adding agar to cold liquid without boiling
- One-to-one substituting gelatin sheets by weight
Three dishes with the swap applied
Fruit jelly
Boil 500 ml juice with 1 tsp agar powder for 2 minutes, pour into moulds, chill. Sets firm at room temperature within an hour.
Vegan panna cotta
Simmer coconut cream with sugar and 1/2 tsp agar per 400 ml; pour and chill. Agar gives a clean slice rather than a wobble.
Gummy sweets
Use high-ester pectin with sugar and acid per packet directions — the same chemistry as jam-setting gives a chewy fruit gummy.
Questions people ask
Is agar a 1:1 gelatin swap?
No. Follow the agar packet or a tested recipe: strength varies, and agar gives a firmer, less melty texture than gelatin.
Which is closest to gummy sweets?
A carrageenan-and-starch blend, or konjac for chew.
Can I swap agar 1:1 for gelatin?
No fixed conversion works for every product. Follow a tested agar recipe or packet directions; agar needs heating to dissolve and sets firmer and less melty than gelatin.
Why didn't my agar dessert set?
Agar only dissolves at a full boil; sprinkling it into warm liquid leaves it inert. Boil 1–2 minutes, and note that very acidic juices weaken the set.
Is there a vegan marshmallow?
Yes — several brands whip aquafaba or soy protein with carrageenan or agar instead of gelatin; they toast similarly.

A substitution is not a nutrition guarantee
Choose a replacement for the job the original ingredient performs: binding, aeration, thickening, fat or flavour. A mushroom can imitate a patty's shape while providing much less protein; a nut cream can mimic dairy texture without its calcium or B12 fortification. Check the actual product and the rest of the meal.
Ratios are starting points unless a complete recipe has been tested with that exact replacement. Brand formulation, water content and cooking method change the result. Try a small batch for important bakes, and check soy, nuts, sesame and wheat allergens even when a product is labelled vegan.
