I actually
found red currants at the market, so bought some and took half and pureed and strained them and made a reduced syrup, added the remaining whole berries, and poured it over the lemon panna cotta.
Proanthocyanidins can be
found in many plants, such as apples, acai, cinnamon, grape seed and grape skin,
red wines, bilberry, cranberry, black
currant, green tea, black tea, and others.
