First, peel those green plantains real careful and slice them thick. Thick slices mean they fry better and mash easier later.
Next, heat the canola oil in a big skillet over medium heat. When it’s hot enough, fry those plantain slices until they’re golden brown, about 5 minutes each side. You’ll smell them getting crispy and sweet.
Remove the fried plantains and drain on paper towels so they aren’t greasy. Then toss them in a bowl and mash ’em up with garlic powder, salt, the very chopped garlic, and the crushed beef bouillon cube until smooth.
On a separate pan, melt butter on medium heat. Toss in the shrimp and sprinkle in garlic powder. Cook shrimp for about 3 minutes till it’s heated through but still tender.
Pour in the lime juice and stir to mix all those zesty flavors. Then fold the shrimp right into the mashed plantains until you get a nice, uniform mix.
Shape your mofongo into mounds or little bowls for serving. You sense the flavor right away and know this part’s worth all the waiting and work.
