Kvass Kvass is a traditional Slavic and Baltic fermented beverage commonly made from rye bread, known in many Eastern European countries and especially in Russia as black bread. The colour of the bread used contributes to the colour of the resulting drink.

It may be flavoured with fruits such as strawberries and raisins, or with herbs such as mint.
Ontbijtkoek An ontbijtkoek (literally translated "breakfast cake") or peperkoek ("pepper cake") is a Dutch spiced cake. Rye is its most important ingredient, coloring the cake in light brown. It is often spiced with cloves, cinnamon, ginger, succade and nutmeg. Several parts of the Netherlands have their own local recipe, of which the most famous is "Oudewijvenkoek" (old woman's cake) which is mostly eaten in the northern regions, and is flavored with aniseed. Ontbijtkoek is traditionally served at breakfast with a thick layer of butter on top, as a replacement for bread. However, due to its sweet taste it is also served as a snack.
