Take a large pot, fill it halfway with water and bring it to a boil.
Cut the pumpkin into four parts and add them to the boiling water. Cook the pumpkin for 30 to 40 minutes over medium heat until it becomes soft. You can check if it’s done by trying to bend the skin with tongs. If it gives, it’s ready, if not, it needs a bit more time.
Once the pumpkin is cooked, drain it and let it cool down. Remove the seeds and separate the pulp from the skin using a spoon.
Weigh the pulp and place it in a bowl. Add half its weight in sugar. For example, if you have 1 kg of pumpkin, add 500 g of sugar.
Grate the zest of half a lemon and add it to a pot with the pulp and sugar. Squeeze in the juice of the same lemon, being careful not to let any seeds fall in.
Cook everything over very low heat for an hour, stirring occasionally to prevent burning or sticking. The “Cabello de Ángel” will be ready when it has that dark caramelized color and the characteristic threads.
Serve and enjoy! You can also preserve it in jars or freeze it for up to a year.
