Fills about 40 espresso cups to serve as a Christmas canapé .
Method for the soup
Melt the butter in a saucepan, add the potatoes and onions, season with salt and pepper, stir well and cover with a butter wrapper (if you have one, or greaseproof). Put on the lid and sweat over a gentle heat for 10 mins. Add the stock, bring to the boil and continue cooking until the vegetables are all soft, add the milk or the milk and the cream, then liquidise the soup and season to taste. You may need to add more boiling stock to thin it out if it is too thick.
While the vegetables are cooking fry the chorizo on both sides in a tiny bit of olive oil on a pan. Take off when it is nice and crisp, reserving the rich amber coloured oil. To serve: put a ladle full of the hot soup into warm espresso cups, (or warm bowls), drizzle with a little pesto and top with about 3 or 5 cubes of cooked chorizo and a drizzle of the oil from the pan over the top.
Method for the kale and walnut pesto
Place the walnuts on a tray and roast at 200°C for 4-5 minutes till golden.
Roughly chop the kale then place in a food processor. Whiz for a few minutes until the kale is quite fine (almost as fine as chopped herbs), it will take a few minutes.
Then add the garlic, the roasted hazelnuts and the cheese and whizz till fine. Add the extra virgin olive oil, taste and add a small pinch of salt if necessary. Pour into a sterilised jar, or 2 small jars, bang down on the work top to remove any air bubbles then pour over the 50ml extra virgin olive oil, cover with lid and put in fridge. This will keep in fridge for 6 months. When you want to use some, pour the olive oil off the top into a clean small bowl then spoon out desired amount of pesto, bang down again on the worktop and clean around the inside of the jar with kitchen paper before pouring the olive oil back in to cover, as before.
