Dear SN,
I fully agree with you on how tamarind paste is handy to us.
Trim green chillies, spread on a plate & dry them in shade - I usually keep the plate on the voltage stabiliser! When it is completely dry, powder & keep.But avoid buying more than 100 gms of green chillies at a time.Besides, th variety that we get now in Chennai, is extremely hot!

Hand blender & hand mixer are different.
Hand blender comes with a blender & mincer & some with a whisker also.The blender churns tomatoes, keerais, lassis, small amounts of soups, blends solids & liquids(I do this when making halwas or mixing 2,3 ingredients for sweets without lump).But cannot knead a dough on its own.
Mincer - minces green chillies, ginger, onions, cabbage, gobi, nuts - chops very fine.
Whisker for lassis, omelettes etc.
Handmixer has 2 sets of 2 blades each - whisking & kneading.
The former is for cake making.
The latter is for dough kneading for chappathi, puri, naan, bakshanams etc.
Love,
Chithra.
