1 packet Marie biscuits (or use 20 vanilla-flavoured wafers), crushed
3/4 cup (6 ounces) melted butter
Combine the crushed cookies with melted butter in a bowl. Press mixture into a 9 x 9-inch foil-lined baking pan
2 (14-ounce) cans sweetened condensed milk
Juice from 2 lemons
1 1/2 tablespoons unflavoured gelatine
1 cup boiling water
Beat together ingredients in a bowl and pour on top of first layer. Refrigerate.
2 (3-ounce) packages raspberry or strawberry gelatine
2 1/2 cups boiling water
Dissolve gelatine in boiling water. When cooled, pour on top of second layer.
Makes about 24 squares.
Note: Be sure to pour the flavoured gelatine (third layer) on top of the second layer before it starts setting – if not, it will not stick.
