That really looks first class LC.

Mid-strength??? WTF?!

Once again, in the link to the mixed powder, there are 2 issues arising.

We have the possibly confusing, and apparently interchangeable, use of the terms "mixed powder" and "curry powder" by the presenter. It is possible to ignore this first issue as the intent is clear enough anyway.

Second is the use of a "curry powder" as an ingredient in the "mixed powder". 
The question of which curry powder is only partially answered in the questions section where it is explained that "Mild Madras Curry Powder" is the ingredient required. However, as we already know there are as many different "Mild Madras Curry Powders" as there are Indian cooking video presenters and the individual spices used in them is not always / ever the same.

So essentially what is happening here is that he is diluting the other spices in what may be a proprietary brand Mild Madras Curry Powder with extra Tumeric, Coriander and Cumin.

It is also interesting to read Goncalo's comment suggesting that this may not be the exact mix used in the restaurant judging from the colour.

Of course you are correct and in the quantities used it is probably irrelevant anyhow.  Also the lighting used in video and photography can affect how the colours look, so it is a bit of a long bow call from Goncalo, to suggest it is not what he actually was using at the time.

Great work again Russ, the curries look amazing .
How did the base compare to Jb base?
