Seperate the eggs
Whisk the egg whites until stiff peaks (easier with an electric whisk if you own one)
fold in the sugar
get a baking tray out
put the sponges on (if there small you might want to put to together)
put a blob of jam on (though if you do use two don’t put the jam in the middle
put a block of icecream on top of each one
and then spread or pipe the eggwhites all over the sponge and icecream making sure not to leave any holes then put them in the oven for 5 minutes and your done!
