Question: I'd like to re-create those pumpkin spice mixtures I've seen for sale in gift shops. What is the right proportion of ingredients?

Answer: Mix the following in a nice gift jar: 1/3 cup ground cinnamon, 1 tablespoon ground ginger, 1 tablespoon ground nutmeg or mace, 1-1/2 teaspoons ground cloves, and 1-1/2 teaspoons ground allspice. Add a gift tag with these instructions: "For pumpkin pie, add 1 to 1-1/2 teaspoons of spice mix to your other ingredients."
