Dulce de batataSweet potato paste
Deep orange and firm enough to slice, dulce de batata is the sweet potato paste Argentines eat with cheese, bake into pastelitos and pasta frola, and pack into school lunch boxes; the classic commercial block often hides a ribbon of chocolate in the centre. Making it at home takes patience at the stove, but the result tastes of real roasted sweet potato and vanilla. Traditional recipes simply cook the purée down for a long time; some factory versions set it with gelatin. This one uses a little agar, a seaweed-based setting agent, so it is reliably firm and stays vegan. Choose pale-fleshed sweet potato (batata) if you can, which gives the classic colour and dense texture; orange-fleshed ones work but set softer. The usual problem is too little cooking, which gives a paste that weeps; it is ready when a spoon drawn through it leaves a clean line. Chef's tip: cover your hand with a tea towel while you stir, because the thick paste spits like lava.
