Ingredients
  

  • 2 ripe plantains, peeled and cut into 8 pieces each (approx. 460 gram after peeling)
  • 4 eggplants, peeled and chopped into chunks (approx. 600 g after peeling)
  • 1 teaspoon salt

Tomato-Onion Sauce

  • 3 tablespoons olive oil
  • 3 scallions, chopped finely
  • 2 cloves of garlic, chopped finely
  • 1 teaspoon cumin powder
  • 6 ripe tomatoes, grated
  • salt and pepper

Instructions
 

Cook plantain and eggplant

  • Place pieces of plantain in a pot with water, bring to a boil, turn low and let cook until soft (10-15 minutes). At the same time, cook the chunks of eggplant in water and salt until soft (15 minutes).

Tomato-Onion Sauce

  • In the meantime, prepare the tomato-onion sauce:
    In a medium-sized pan, cook onion and garlic on a low heat in oil until soft (5 minutes). Add cumin and cook for an additional 2 minutes until fragrant. Add grated tomatoes, salt and pepper to taste, and let simmer for about 20 minutes, until the sauce has a darker red color and lost some of its liquid.

Finish mash

  • Check if the eggplant and plantain are cooked, drain and mash with a fork. The mash shouldn't be completely smooth. Adjust seasoning of the tomato-onion sauce if necessary. Add half of the sauce to the mashed vegetables and mix well. Taste and adjust seasoning.
    Serve while warm with a teaspoon of tomato-onion sauce on top.

Notes

The ratio plantain-eggplant is important. Adding too much plantain will make the mash overly sweet. You want about 1/4-1/3 more eggplant in comparison to plantain.
