Within a heavy-duty soup pot heat the oil on medium heat and fry the chorizo for two minutes.
Decrease the heat and mix in the onion, garlic and chilli. Gently cook for 10 minutes, or until the onion has become tender.
Pour the white wine into the pot and lightly simmer for an additional minute to evaporate the alcohol.
Incorporate the potatoes and stock and mix well. Add the paprika, celery salt and tarragon, stir thoroughly and return to boiling.
Reduce the heat to low and gently simmer until the potatoes are thoroughly cooked. Add a little boiling water to the pan if it looks like there’s not enough liquid.
Season with salt and pepper to taste. Garnish with a scattering of the almonds, a dash of parsley and a fine drizzle of olive oil.
