There's something that really irks us when we read over a new curry recipe and see "curry paste, found in the international aisle" listed as one of the ingredients. Not only have we rarely found curry paste at any grocery store, but this seems like something we should be able to make ourselves. Apparently Jamie Oliver agrees!
We recently discovered Jamie Oliver's instructions for five basic Indian curry pastes on his website and did a little dance for joy. These recipes call for ingredients that aren't too much trouble to find (fenugreek seeds might be the most exotic), and are easily prepared in a food processor or blender. They make enough for one batch of curry, but could easily be doubled or tripled to make extra to have on hand for later.
Now we're no experts and these may not be the most authentic curry paste recipes ever, but they certainly get the job done. So far we've tried the korma and the tikka masala, and had fine results with both. For certain these are a far sight better than any jarred sauces we've tried over the years.
Do you make your own curry paste?

store bought is crazy expensive - i've seen them from $5-10.
I love to make my own curry paste. It definitely tastes miles better than a bottled sauce! This penang curry paste was similarly adapted to use ingredients you could find at a well stocked grocer (no trip to an Asian specialty shop needed).

For cheap store bought curry paste try this brand:
http://www.amazon.com/Mae-Ploy-Green-Curry-Paste/dp/B000EIE20M/ref=sr_1_1?ie=UTF8&s=grocery&qid=1279216810&sr=8-1
I have seen this brand at the grocery store as well as World Market stores for a similar, if not cheaper price.
I cook Indian all the time and would never use a pre-made paste.
However - for Thai cooking pre-made pastes are common. I cook Thai from scratch (pounding the pastes from raw ingredients in a mortar & pestle and all), and even I would say there are some good Thai curry pastes available in markets. I like the Mae Ploy brand in tubs. It's a fine shortcut.
I love this curry recipe from Gordon Ramsay:

I make a bunch of the curry paste and freeze it in batches.
