Plant-based desserts with agar agar: drinks, fats and structure

A plant-based drink is more than milk without animal ingredients: it has a different balance of protein, fat, sugar and water. When designing an agar agar dessert, these differences matter as much as the gelling agent dose.

Choose the base

Soya, almond, oat and coconut drinks do not automatically give the same texture. Check ingredients already present in the purchased product: some contain starches or stabilisers that contribute to structure.

Agar agar works in the water phase. It does not dissolve in pure oil and cannot, by itself, reproduce all the balances of a traditional mousse or cooked cream. Increasing the dose can make the dessert firmer without providing the creaminess you want.

Organise a trial

Weigh the base, choose a suitable recipe and dissolve the agar fully with appropriate heating. Pour a sample into the mould and let it cool. Taste the dessert cold and judge whether the portion is pleasant, not just whether it holds its shape.

If adding a purée after heating, avoid a temperature shock that sets the gel before the mixture is homogeneous. With highly acidic fruit, avoid unnecessary time at high temperature and check the formulation.

Ideas to start with

The mango and coconut terrine demonstrates working with two layers. To understand the difference in bite, read the comparison with animal gelatin. Check the entire ingredient list: a plant-derived gelling agent does not automatically make the whole recipe vegan.
