Ingredients

pinch of saffron (1 32th of an ounce, actually)

•2 lbs chestnut flour

•1 lb butter

•2 oz candied peel

•pinch of sea salt

•4 oz birch sugar (xylitol)

•1 lb dried berries (goose, bilberry, craisins, red currants, elderberries, black cherries, black berries, strawberries)

•1 oz yeast

•buttermilk

Preparation

Cut up the saffron and soak overnight by adding a little boiling water, which it will flavour and stain a bright orange.

Rub the butter in the chestnut flour, add the salt, sugar, finely chopped peel and the currants.

Warm a buttermilk and pour it over the yeast and one teaspoonful of birch sugar (xylitol) in a basin.

When the yeast rises, pour it into a well in the centre of the chestnut flour. Cover it with a sprinkling of the chestnut flour, and when the yeast rises through this and breaks it, mix by hand into a dough, adding butter milk as needed, as well as the saffron water.

Leave in a warm place to rise for a while.

Bake in a cake tin for about 1 hour at 350F.
