Is kasza semolina different somehow from semolina?
Kasza (or kaszka) manna - known under the American brand name: "cream of wheat", or "wheat groats" in general - is made from
regular wheat, while
semolina - from
durum, hard, wheat. Semolina is used in industrial production of pastas, couscous, bread and cakes. Semolina comes in various sizes (including fine flour size), while kaszka manna is more of less of the same standard, fine groats, size. Flower and bran fractions are removed during purification process of kasza manna.
As you have said - semolina is more yellow, while "kasza manna" should be white with a yellowish tinge. The latter contains very little fibre, minerals and vitamins, but large amount of starch.
Durum wheat or macaroni wheat is the only tetraploid species of wheat of commercial importance that is widely cultivated today. (wikipedia)
