Gambas al Ajillo (Spicy Shrimp and Garlic)

My friend, Ultimatejo Tan recommend me to try out this dish which is really superb that I have made it few times in a month.  Thank you, Jo for your recommendation

Recipe adapted from a website but cannot remember the web link. Below is the recipe I copied down in my notes

Makes 2-4 appetizer servings
1/4 cup olive oil...
6-7 garlic cloves, finely chopped
1/2 teaspoon red chile flakes
1 thai bird chile, finely chopped
1 pound shrimp, peeled and deveined
1/2 teaspoon smoked Spanish parika
Optional–1 tablespoon banana ketchup (can be found in Filipino markets)
juice from half a lemon
Salt and pepper, to taste
Chopped parsley for garnish

Heat the oil in a large saute pan over medium-high heat. Add the garlic, chile flakes, and chile to the pan and cook until garlic just begins to brown, about 30 seconds.

Add the shrimp and paprika to the pan and toss to coat. Cook the shrimp until they turn pink and are just cooked through–about 3 minutes.
