Yeast and Rye Bread
Yeast (kvasac) is an essential baking ingredient. When stating what ingredients you are baking with, use the preposition s (with) followed by the instrumental case. For a masculine noun like kvasac, this changes the ending to -em (s kvascem).
Rye is raženi. Use this adjective to specify the type of bread (kruh).
Wholewheat Bread and Rolls
Another common type of bread is wholewheat (integralni).
For a smaller bite, reach for a roll or pastry (pecivo). Because pecivo is a neuter noun, modifying pronouns like ovo (this) or ono (that) must match its gender.
Seeds and Sesame
A seed is sjemenka, but you will usually encounter the plural form, sjemenke.
Sesame is sezam. Just like with yeast, when talking about eating bread with sesame, use the preposition sa (a variation of s) followed by the instrumental case (sa sezamom).
Sunflowers and Crispy Crusts
Sunflower is suncokret. To say sunflower seeds (literally "seeds of the sunflower"), use the genitive case: sjemenke suncokreta.
A crust is kora, and crispy is hrskav. In the accusative case (when describing what a bread has), the feminine noun kora becomes koru, so its adjective changes to match (hrskavu).
Corn Bread
Finally, corn bread is kukuruzni kruh. When baking it in the oven, use the preposition u (in) with the locative case (u pećnici).
