In heavy 2-quart saucepan, mix 3/4 cup sugar and the water. With pastry brush dipped in water, wash any sugar off inside of pan. Without stirring, cook over medium-high heat 5 to 6 minutes or until mixture begins to turn amber in color. Gently swirl pan as mixture darkens to golden brown (watch carefully, as mixture can burn in seconds). Immediately remove from heat. Carefully pour over apples in custard cups. Place custard cups in 13x9-inch pan.
