Couscous with water and rolled with the hands to form small pellets, sprinkled with dry flour to keep them separate, and then sieved. Any pellets that are too small to be finished granules of couscous fall through the sieve and are again rolled and sprinkled with dry semolina and rolled into pellets. This labor-intensive process continues until all the semolina has been formed into tiny granules of couscous. In the traditional method of preparing couscous, groups of women came together to make large batches over several days, which were then dried in the sun and used for several months. Handmade couscous
Birbeck granules periphery of the Langerhans cells and release their contents into the extracellular matrix. Another theory is that the Birbeck granule functions in receptor-mediated endocytosis, similar to clathrin-coated pits. Birbeck granules were discovered by Michael Stanley Clive Birbeck (1925–2005), a British scientist and electron microscopist who worked at the Chester Beatty Cancer Research Institute or Institute of Cancer Research, London from 1950 until 1981. Birbeck granules Birbeck granules, also known as Birbeck bodies, are rod shaped or "tennis-racket" cytoplasmic organelles with a central linear density and a striated appearance. First described in 1961 (where they were simply termed "characteristic granules"), they
