Makes about 3 Cups (enough for 8" double layer cake)
With hand mixer, beat egg whites
until foamy in the top of a double
boiler, set about 2" from the simmering
water. Beat in remaining ingredients and continue beating for about seven
minutes (hence the name) or until temperature on a candy
thermometer reaches 160° F and soft peaks form. Remove top of
double boiler and continue to beat until stiff peaks form, about 4-5 minutes.
