Red palm oil is really of a strong red-orange color, it is very cheap and easy to find in ethnic shops, it comes almost exclusively from west Africa countries and Africans from those countries are likely the main buyers here in Europe.
I buy the most expensive I can find and it is 5 euro for 1 liter, I am not sure about the quality difference with the ones costing just about half that price, probably there isn't any but 1 liter last forever to me and the price gets quite irrelevant.
By the way I find it quite beneficial on hair and skin, it does stain skin and pillow of yellow.
I am not sure adding ginger would be of any help, I prefer ginger in teas or as juice.
Adding pepper might enhance curcumin bioavailability but make sure first you are OK with it.
Just made another batch yesterday, red palm oil now is liquid at room temperature (we are well above 25 Celsius now) but after turmeric is added, heated in double boiling and cooled down in the fridge for a few minutes it turns solid like margarine and stays solid at room temperature, weird but real.
Olive oil will do but turmeric sinks to the bottom making it a little impractical, that's why achieving a solid consistency is preferable in my view.
