The pantry

I read all of these books. In one of them, the naughty little sister and Bad Harry go to a party. They find the birthday cake, which has been hidden from the children. Between them, they eat all the cream and the lollies (called sweets) that decorated the cake. I remember there were jelly babies treading through the cream. And silver balls. They ate until they felt ill. Then the mother found them in the pantry. The pleasure of the stolen cake and the jelly babies treading through the cream. The tiny silver lollies in the dark pantry. What was a pantry? Suddenly, when I was seven, I loved pantries.
