Scallops: add the butter (1st lot), scallops, salt and pepper and cook the scallops for 3-4 minutes per side.
Butter and oil: next without rinsing or cleaning the pan, add the 2nd lot of butter, the olive oil, garlic and onion. Stir to combine and let this mixture cook for 1 minute.
Rice: next add the arborio rice to the hot pan and stir to allow this to get coated in the butter and oil mixture. Once it has, pour in the white wine and stir to allow it to mix in.
Chicken stock: next gradually add the chicken stock to the pan, continuing to stir and allowing it to slightly absorb before adding more of it.
Peas, asparagus and parmesan: next add the frozen peas to the pan and stir, allowing them to defrost and thaw before heating through. Once the peas are cooked (1-2 minutes), add the asparagus, give it a stir to mix it in and allow it to soften (1-2 minutes) then add the parmesan cheese and stir till it is consistently mixed into the risotto.
Scallops: next add the cooked scallops back to the pan and allow them to heat through.
To serve: once the scallops have heated through, turn the heat off, give the dish a generous sprinkling with freshly grated parmesan cheese, a touch of black pepper, provide bowls, forks and spoons then head to the table.
