Make the sauce
Place Chef Series II 11"/28 cm Fry Pan over medium high heat and add butter. Melt butter and then wait for it to start to brown. Once it begins to take on a brown color and smells nutty, about 2 minutes after melting, remove from heat.
Whisk lemon zest and juice into warm butter.
Toss and serve
Strain cooked pasta and place in large bowl. Toss with browned butter sauce and chopped walnuts. Adjust seasoning to taste and serve topped with fresh basil and sliced pears, if desired.
