1. I always grind my ginger and garlic separately. This way, you can control what goes into your dishes.
2. My umma grinds equal quantity of ginger and garlic to make ginger-garlic paste. I have seen that some use a proportion of 3/4 part of garlic to 1 part of ginger. I guess it's totally upto your choice. I still prefer to grind them separately.
3. To peel garlic easily, give the garlic a nice hard press, drop into a bowl of water for 5 minutes and start peeling. It would come off quite easily.
4. I'm yet to discover an easy way of peeling ginger. Anybody can help me out, please??? :)
5. Do not store garlic paste on the refrigerator door. This will make the garlic color move from yellow to green. Even though you still can use it, the green color does not look really appealing.
