A curry paste is a wet mix of spices, herbs and seasoning cooked with oil and vinegar which helps to preserve them during storage. If you want to make a paste, it is a question of cooking a quantity of spices along with some oil and vinegar. For example use a curry masala to make a curry paste or a tandoori masala to make a tandoori paste.
There's no hard and fast measures here but as a starting point I would suggest trying 1/4 pint of oil and 1/4 pint of vinegar and mix in a bowl with maybe a total of 10-12 tablespoons of spices including salt and dried mint if you want. Pop your wok on a medium heat, drop in your wet mix and cook until the water evaporates off and the oil separates. This is rather like cooking a curry but it will take slightly long due to the quantity of spices but certainly no more than ten minutes.
You can then spoon the paste into a glass jar, and put a small layer of oil on top to help preserve your paste. This should keep for 3-4 weeks in the fridge.
