You will need some small bay scallops and shrimp (I use the frozen ones because they are already cleaned, peeled and all of that), whipping cream, red onion, minced garlic, fresh Parmesan cheese, salt, pepper, your favourite pasta, a very big skillet for the sauce, some flour for thickening(like just a little tiny bit) and whatever other spices you feel like might complement your tastes. I used a little dill and garnished with cilantro.
Dice up that onion and saute it with the garlic. I use extra virgin olive oil because it is the best!!
Add in the scallops and shrimp and then throw in your salt and pepper and dill or whatever spice you like for this.
Add the whipping cream and a little flour, bring it to a boil and keep stirring. Cool it down and throw in your cooked pasta.
Once it is thickened up and cooled a little, put it in a bowl and then garnish however you like.
