Lime buttermilk quark cake with biscuit base

Ingredients for 1 servings:

• 200 g rusks or butter biscuits
• 100 g butter or margarine
• 3 lime(s), organic, juice and zest
• 500 ml buttermilk
• 5 sachets of agar-agar, each for 500 ml of liquid
• 5 tbsp sugar
• 1 packet of vanilla sugar
• 500 g low-fat curd cheese
• 250 ml whipped cream
• 2 limes
• 1 tsp sugar
• 1 tsp, heaped cornstarch
• 50 ml water

Instructions

Working time approx. 25 minutes; Rest time approx. 4 hours; Cooking/baking time approx. 10 minutes; Total time approx. 4 hours 35 minutes

refreshing, without gelatin, no baking, from a 26 cm springform pan, approx. 8 pieces

Crumble the rusks or biscuits (either in a cutter or fill portions into a freezer bag and roll over them with a rolling pin) and place in a bowl. Melt the butter, pour it over the crumbs, and mix well. Line the bottom of a round springform pan (26 cm) with baking paper. Pour in the butter and crumb mixture, smooth it out, and press it firmly into the bottom. Place the pan in the refrigerator. The bottom will not bake! Wash the limes in hot water, zest, and squeeze out the juice. Place both in a saucepan along with the buttermilk, agar-agar, sugar, and vanilla sugar and bring to a boil while stirring gently (be careful, the mixture boils just as hot as regular milk!). Simmer for 2 minutes while stirring. This is important so that the agar-agar thickens. Let the lime buttermilk cool, stirring frequently (I place it in a cold water bath; it’s faster). Whip the cream until stiff peaks form. Once the lime buttermilk has cooled slightly and begun to set, stir in the quark and then fold in the stiffly whipped cream. Pour the mixture onto the crumb base, smooth it out, and chill in the refrigerator for at least 4 hours. For the glaze, boil the juice of 1 lime with 50 ml water, sugar, and cornstarch, stirring continuously. Pour the glaze onto the cake and spread it gently with a pastry brush. Then chill the cake. Tip: If you have any leftover limes, you can arrange thin slices of lime on top of the set cake as decoration.
