Yeah I know a lady same like your's auntie. She asked for a good recipe from every friend but when she made some thing in a year and when we asked she replied add all ingredients in it (saray masalay daal ker bhoon lo) but we surprised what masala, all spices in the kitchen cabinet is not for all recipes, so now nobody share any recipe with her except one of our friend help her, we think she missused all of us. So we keep us away from her and met in formal way not like we met before.
There is a funny event happend with me, when I came to US after marriage, one of my hubby's friend invited us for dinner, after dinner dessert is served, she made it yummy, I asked the recipe, she told me their is milk, sugar, eggs and almond in it, when I asked how much is the quantity she replied I don't remember the quantity, I got surprised, when we were back I think how can anybody cook food and after few hous she don't remember the quantity, I googled the recipe having same ingredients and the result is Baked Egg Halwa, then I made the same dessert after one week till now several time and shared recipe with most of my friends who asked the recipe.
