Here's probably my last entry:
Green Mango Chutney
Mangoes are abundant here in Venezuela; almost every house has a mango tree ( I've got two) and, during the high season, fruit falls to the ground and is mostly wasted or eaten by birds and animals.
If you search for mango chutney recipes in internet, you'll probably get millions of hits. This particular recipe is an adaptation of (a) my first attempt in 2004, which also had tamarind and (b) a recipe given to me by a wonderful Indian cook called Mamta.
If you can only find ripe mangoes, then that's fine; just lower the sugar content a bit. If you like your mango chutney dark, then add a handful of raisins or currants and, again, lower the sugar content a bit. If you like it as they do in the Caribbean, then triple the amount of chile powder or chile peppers. The acidity (green) or sweetness (ripe) of the fruit will balance the results.
As for the nigella seeds; I just love them. Nigella has to be one of my favourite spices. If you haven't got any, or don't want to use them, that's fine. With the other spices, if you decide to use commercial mixed spice, which tends to be a bit bland, then feel free to increase the amount indicated in the recipe.
