                The usual way to make this recipe is with Rice Crispie cereal, but it is hard to find in Japan. So just substitute any unsweetened cereal such as cornflakes or riceflakes, or a mix of several unsweetened cereals.
                 
                Melt 2 Tablespoons butter or margarine in a saucepan 
                Add 40 large marshmallows and mix constantly over low heat until no lumps remain
                turn off heat and mix in 6 cups cereal
                Press into greased pan with greased hands 
                Let cool and cut into squares, or other shapes, such as stars
                 
                Alternative--add 2 Tablespoons cocoa or 1 teaspoon cinnamon  to melted butter for different flavors
                 
                This is a very versatile recipe that can be adapted for almost any holiday.
