In a large pot of boiling salted water, cook penne until tender but still firm, 10-12 minutes; drain well. Return pasta to pot. Add cream, curry powder, and scallions. Cook over medium heat, tossing gently, 8-10 minutes, until thickened slightly. Stir in lemon juice and shrimp; heat through. Serve topped with a sprinkling of grated Parmesan cheese, if desired.

Serves 2 very generously.
