commercially. As mentioned above, I can't have bulbs of garlic in the house because my cat finds them to be Great! Fun! To! Bat! Around! The! Kitchen! and even more great fun to chomp on, then come wake Mommy up by breathing garlic cat breath in her face at 3 am. (The only time I have ever believed in demons or monsters is when I wake from dreams to that smell....) So I just use chopped garlic in oil (it comes in bottles at most supermarkets; major brand name is Christopher Ranch). You can use plain garlic - 4-5 cloves.
You can do the same with fresh ginger root - ginger paste for me is the logical thing that happens after I buy a hand of ginger - it comes home, it gets peeled, and it goes in the bowl of the handi-mixer until it's paste. A few drops of lemon juice as a preservative and it will last in a babyfood jar in the fridge for a couple of weeks. You can also just use plain, fresh chopped ginger. (In my climate, if I buy a hand of ginger and leave it on the counter, I have this mummy looking thing in about 48 hours; if I leave it in the fridge, it usually gets lost and becomes icky. So....) I think Christopher Ranch has a jarred ginger paste and I know that it comes in tubes like toothpaste, too.
Tiger Tiger is a name brand of sauces and condiments that is popular in England as a convenience food. It's the equivalent to Prego or Ragu, but with far superior taste and better ingredients. It's an all natural, pre-made and bottled sauce that we buy at Cost Plus World Market occasionally (when we know I'm going to have a lot of evening client meetings). I haven't seen it any place but CPWM except in England, and right now, the budget doesn't let me make regular shopping trips to Harvey Knickers ^H^H^H^H Nichols and Harrods. A-hem.
Finally, Garam Masala is a finely ground Indian spice mixture. There are literally hundreds of variations, but you can make your own and adjust it to your own tastes. Here's one that's close to mine and has the directions; you can also buy it at many Asian groceries. (I add mustard seeds, sesame seeds and nutmeg; we also make a Kashmiri version and my husband the human fire eater makes a Mumbai mixture that I can't even touch that he uses for vindaloo....)
