I have not heard of nutty wheat flour, which I would assume to be flour with crushed nuts inside. If nutty wheat flour is a type of whole-wheat flour, then you should know that there are various kinds in Israel. Sugat and Ta'am Teva package an excellent quality whole-wheat flour. Harduf packages organic white and whole-wheat flours. You can find these flours in health-food stores and some supermarkets.
Many recipe books refer to summer and winter squash.
Both summer squashes and winter squashes are gourds, but unlike winter squashes which are harvested mature with hard outer skins and tough seeds, summer squashes are harvested when immature, making their skins and seeds edible. Light-skinned summer squash are called kishuim in Hebrew, while the dark skinned variety is called zucchini in both Hebrew and English. You can sometimes find yellow kishuim as well, but these are mostly for export. Tamarind concentrate is made from the tamarind pod, also known as the Indian date. The pods contain small seeds and a sour-sweet pulp that when diced becomes extremely sour.
