    1 1/2 cups self-raising flour
    1/2 tsp vanilla essence

    1 cup Chelsea White Sugar

    1/2 cup milk
    2 Tbsp custard powder
    2 Tbsp cornflour

    Cream butter and Sugar. Add egg, flour, and vanilla essence. Mix well then press into a well-greased slice or sponge-roll tray. Bake for 15-20 minutes at 160°C until pale golden coloured. Cool.

    Put Sugar, water and the juice and rind of the lemons in a saucepan and bring to the boil. Separately mix the milk, custard powder and cornflour to a smooth paste. Stir in the 2 mixtures together using a wire whisk, then slowly bring to the boil and boil for 3 minutes. Pour over the shortcake.

    In a medium-large saucepan dissolve gelatine in the water. Add the Sugar and boil for 8 minutes, then cool. Add the lemon essence and Icing Sugar and beat until thick and creamy. Pour at once over the shortcake and filling and leave to set. Cut when cold.

It was tasty and very good combo of sweet and sour

Base and filling are amazing but there isn't enough marshmallow topping mixture.

Super yum! Will definitely make this again!

Havent made this yet just wondering if it's possible to swap lemon essence for lemon juice? Looking forward to trying this recipe as the traditional marshmallow slice doesnt last long in my house.
CHELSEA: absolutely lemon juice would work just as well. Yum!

turned out perfect - very sweet. Yes you do need a high tin for this.

Great combination but the marshmallow did not pour on. Maybe I cooled it down too much.

A wonderful great tasting slice!

Delicious combination of sweet and sharp. Only problem was the marshmallow trying to slide off but it still tastes divine.

what size tin is good for this?

Yum, the best lemon slice we have ever made - this one didn't hang around long in our pantry!

Very yummy ... But the marshmallow kept sliding off the top. Also, you need to have a tin with quite high sides, as the topping layers up high!
