Heat a 2 inch deep-sided sauté pan. Add butter and olive oil. Sauté shallots until transparent. Add littleneck clams and wine. Cover and let simmer until clams open. Season with lemon juice, salt and pepper. Set clams aside. Reserve clam juice for risotto.
Preheat another sauté pan and add olive oil, butter and shallots. Sauté until shallots are transparent. Add rice and pancetta. Toast slightly and let rice absorb the butter and olive oil. Deglaze rice mixture with wine. Add fish stock a little at a time, letting rice absorb all the liquid before adding more. Keep adding liquid until rice is al dente. Add reserved clam juice, lemon juice, sweet peas and chopped parsley. Season with salt and pepper and add unsalted butter. Toss reserved open clams into the risotto.
