Use a 12" round pan, on high heat get the pan nice and HOT. Then add 2TB of oil into the pan and add shrimps making sure not to overcrowd the pan. You should hear a sizzling sound once you add the shrimps. Sear the shrimps on both sides just until they turn pink.
Once you turn the shrimps to another side, sear for another 30 seconds or so and add 4TB of white wine, 1/2cup of Heavy cream, and 6TB of bbq butter.
Incorporate the butter into the sauce and reduce just a little bit until the sauce bubbles and thickens a bit. (about 2-3 min) Take off the heat right away making sure not to overcook the sauce because it will separate if overcooked.
Garnish with green onions and serve immediately.
NOTE: If you do happen to overcook and the sauce separates, don't panic! Add another 1-2TB of Heavy cream and it will come back together. Take off the heat immediately.
