1.Combine pumpkin, onion and garlic in a saucepan, add 200ml water, then cover and cook over low heat until pumpkin is tender (50 minutes-1 hour). Remove lid and cook until most of the liquid evaporates (15-20 minutes). Remove from heat and drain off any remaining liquid. When cool enough to handle, remove and finely chop the onion, then place in a bowl. Squeeze cooked garlic cloves from their skins into the same bowl, add pumpkin and 1 tsp sea salt and combine well. Place a double-layered square of muslin in a bowl, pour in pumpkin mixture and tie the cloth with string. Hang in refrigerator overnight, suspended over a bowl to drain. The mixture should yield just under 1kg of pumpkin pulp.
2.Finely mince the chilled back fat with the mincing attachment of a food processor or a hand mincer (see note). Combine drained pumpkin mixture, paprika, oregano, cloves and 3 tsp sea salt in a bowl. Add minced fat and mix together well. Place in a 700ml serving bowl or dish, such as an earthenware cazuela. Cover tightly with plastic wrap and refrigerate until firm (24 hours).
3.To serve, spread a little on toasted bread or crackers and enjoy with beer or light red wine.
Note Alternatively, ask your butcher to mince the back fat for you.
