Koldskål
Cold buttermilk soup
Koldskål: Danish cold buttermilk soup with lemon and vanilla
On the first warm day of summer, Danes buy cartons of koldskål and packets of kammerjunker, small crunchy rusks, and the season has begun: koldskål is a cold, sweet, tangy buttermilk 'soup' with lemon and vanilla, eaten from bowls as a dessert or a light supper, sometimes with strawberries. Homemade, it is whisked with egg yolks for richness. Raw egg yolk is not suitable for pregnant women, young children or anyone with a weakened immune system, so this recipe uses pasteurised egg yolks. A common mistake is serving it at room temperature; it must be very cold. Chef's tip: whisk the yolks and sugar until thick and pale before the buttermilk goes in, which gives a silky, foamy soup.

Kartoshka cakeCocoa and cake crumb truffles
Soviet cafés and school canteens sold these knobbly brown 'potatoes' for a few kopecks, and they began as a thrifty way to use up sponge and biscuit trimmings at the bakery. Crumbs are bound with butter and sweetened condensed milk, flavoured with cocoa and vanilla, shaped into little potatoes, rolled in cocoa and finished with two dabs of pale butter cream for the sprouts. They are fudgy and dense like a brownie truffle, need no oven, and children love making them. Traditional bakers added a spoonful of rum, an optional extra for adult batches only; this version is alcohol-free with vanilla. The usual slip is coarse crumbs, which make the potatoes crack, so blitz them as fine as sand. Chef's tip: chill the shaped potatoes for at least 20 minutes so they hold their shape and slice cleanly.

Undu walaluFried urad dal rings in treacle
Walalu means bangles, and these dark, sticky rings of fried urad dal soaked in kithul treacle are a sweet that Sinhala families bring out for Avurudu and for special almsgivings, often made in large batches by an aunt known for her steady hand. A thick, fluffy paste of ground black gram is piped into loops and fried until crisp, then plunged straight into warm treacle, so the rings stay crunchy on the outside while drinking up the syrup. They taste a little like a darker, smokier jalebi, with a toffee finish from the palm treacle. Watery batter is what ruins them; it spreads into flat blobs, so grind the soaked dal with as little water as possible and beat it until light. This recipe uses no asafoetida, so it is naturally gluten free. Chef's tip: pipe the rings onto small squares of baking paper and lower them into the oil paper and all; the paper peels away in seconds.

MarquesitasCheese and cajeta crepes
Evening in Mérida's Plaza Grande means the smell of marquesitas: thin batter pressed in hot hinged irons until crisp, then rolled like a cigar around grated Edam cheese and a sweet filling such as cajeta, chocolate-hazelnut spread or jam. Edam came to the Yucatán through the port trade with the Netherlands and became part of the local cooking, and the salty-sweet combination is the whole point. At home you can cook them in a thin, wide frying pan. Edam is usually made with animal rennet, so check the label or use a vegetarian Gouda-style cheese. Chef's tip: roll while the crêpe is still in the pan and hot; within seconds it hardens and will crack.
