They are pretty fiesty; I chucked in a whole chipotle into this recipe and the results set alight to the mouth; ideal for me, really. What you get is a gorgeously sticky, sweet, tangy and fiery sauce to dip your whatevers into. Sweetcorn fritters were my dipper of choice this time, but I imagine some totopos (that's nachos, innit?) would make a good vehicle too. When I ran out of fritter I just used a spoon.
You can buy chipotles in Bethnal Green, at Casa Mexico. You can also shop there online.
Chipotle & Tamarind Ketchup
1 chipotle chilli
1 decent tin of plum tomatoes
Half a white onion
1" of ginger
2 cloves of garlic
2 sprigs of thyme
1 tsp tamarin pulp
2 tsp sugar
1/2 tsp salt
In a small saucepan, simmer the chipotle chilli in water for about 20 minutes, until soft. Either remove the seeds or leave in whole. Mince finely with the onion, garlic, ginger and thyme (I used a mini chopper) and then add a little oil to make a paste. Fry this on a low heat in a saucepan for a good 10 - 15 minutes until deep brown and fragrant.
Drain the juices from the tin of the plum tomatoes (save it for your bloody mary...) and then pulverise the tomato. Add to the chilli mix, season, add the tamarind and the sugar and simmer on the lowest heat for a good 40 - 45 minutes, stirring occasionally. It will initially make plopping fart noises, decorating your hob with specks of red until the liquid separates a bit.
After this, work the sauce through a fine mesh - unless you like it slightly chunky, in which case don't.
