2Tbspground Coriander Seedsif you can't find it already ground, then use Coriander Seeds, dry toasted in a skillet then ground in a coffee grinder or spice mill
1TbspCumin Powder
½tspground Black Pepper
1tspChili PowderCayenne works well
1tspTurmeric Powder
2tspGarlic Powdernot garlic salt
2tspGinger Powder
1tspwhole Brown Mustard Seeds
6 - 8TbspWhite Wine Vinegaror just enough to create a paste, adding 1 Tbsp at a time until you have a paste like consistency
Small handful a fresh Corianderor to taste and to be added when making the curry
Instructions
In a small bowl, mix together the Coriander through to Brown Mustard Seeds.
Start to mix in the Vinegar, 1 Tbsp at a time until you have a paste. I usually end up adding between 6 - 8 Tbsp.
Store in an airtight container in a dry cool place or refrigerator.
The final ingredient, Coriander, is added fresh when making your curry.
Notes
Because of the addition of the Vinegar and since there are no oils, I find that this keeps well stored in my spice cabinet. If you are hesitant to store the mixture this way, you can either keep it in the refrigerator, or the other option is to mix only the powders together. Then when you are ready to make the curry, you can add the Vinegar in along with the fresh Coriander creating your Madras Curry Paste. This paste is used along with lemon juice as the marinade for my favorite Madras Chicken Curry.
