The amount is calculated for a jam jar with 450 ml content.
Put the berries in a tall bowl to thaw.
Rub the peel of 2 limes, then squeeze all 3 limes. Add the lime juice and the lime zest to the thawed berries and puree them finely with a magic wand. Then pass through a fine sieve so that any pips of blackberries, currants or raspberries do not get into the mixture.
Mix the butter with the 4 eggs and the sugar in a saucepan. Add the pureed, sifted berries and slowly heat the mixture, stirring constantly, until it thickens. Just heat it - never bring it to a boil. The mass would curdle immediately!
Spread the berry curd through a fine sieve again and fill it to the brim in a 450 ml twist-off glass. Close tightly with the lid and allow to cool. Chill until use.
This berry curd gets a wonderful color and is an eye-catcher on every breakfast table. It tastes good on rolls or white bread and especially on freshly baked yeast plaits. It is also always well received as a small gift from the kitchen.
