Pumpkin boiled, mashed and finished with butter, milk, broth and a spoonful of hogao, the Colombian sofrito of onion, garlic and tomato. That last ingredient is what separates it from every other pumpkin mash. Twenty-five minutes, four servings.
Hogao is the Colombian sofrito: onion, scallion, garlic and tomato cooked slowly in oil until the tomato collapses into a sauce. It is what makes this a Colombian mash rather than a plain one, and it is worth making properly rather than rushing, because undercooked hogao tastes of raw tomato. Add the liquid gradually. Pumpkin holds very different amounts of water depending on how ripe it is and how long it boiled, so the milk and broth are a guide rather than a measurement: stop when the mash falls slowly off the spoon. If it does go too loose, put it back over low heat and let some of the water steam off.
