heat oil to a shimmer in a small saucepan over medium low heat
Add garlic cloves, and toast until they take a golden color
Remove the garlie and all but ~ 1 tsp of the oil, add the various spices and cook until ragrant, and have formed a paste. Thin with oil a few drops at a time if the paste is too thick
Remove spice paste to cool completely.
To a small mixing bowl add the mayonnaise, Greek yogurt, lime juice, salt, pepper and cooled curry paste.
Mix well and refrigerate.
Notes
One COULD used the seeds of a lot of these spices, dry toast them in a frying pan, thence cool and grind, and continue as above. For that rich nutty, smokey taste.One can also cheat beyond all belief and use a prepared Indian Curry Paste, mixed with mayonnaise, and rested in the fridge for 1/2 hour whilst the potatoes roast.------For the Chipotle Aioli, take 1 cup mayonaise, add 1 tbsp minced Chipotle, and 1 tsp Adobo sauce, 2 tsp lime juice, and 2 minced garlic cloves. Mix well and refrigerate.-----Herbal is some much simpler.Take 1 cup packed fresh mixed herbs, (mint, basil, chives, tarragon), 1-2 garlic cloves, 2 tsp lemon juice, blitz with a food processor. Mix well with 1 cup good mayonnaise. Mix well and refrigerate.One can also make one own mayonnaise. But that is a different post.
