No probs, the base should taste quite nice as it is, this then helps fortify the second stage of any Curry you make & if you do make slight errors the underlying flavor of the base helps to mask then, this is why this & other slightly more complex tend to give better uniform results.The old margin for error philosophy etc..etc.. Cheers for now. ;D
If you want to try my Base you can do it with only 12 Onions (leave all the other ingredients as they are though). I've done it once before when i ran out of Onions & it made no difference. But.... Remember my base is already scaled down from a 30 Onion base which is used by my friendly local Bir, the 15 Onion version on this site is used in the quietest part of the season were they might only get 30 customers or less all night. If you scale down you cannot guarantee the base will turn out as intended & therefore you may judge it incorrectly & be missing out.
