Green's Lemon Pie Filling - 140g

Lemon meringue pie sits right at the heart of the British pudding table, alongside the crumble and the trifle. It is the one that looks impressive and tastes sharp enough to wake you up after a roast, and a packet of Green's has been the quiet shortcut behind plenty of them.

People in Canada go looking for it because the pie they remember had a particular taste and a particular wobble. Get the filling right and the rest is just pastry and egg whites, which most of us can manage.

It comes as a 140g packet that sits happily in the cupboard until the craving hits. Follow the instructions on the pack, set it in a baked pastry case, then top with meringue. Some people skip the meringue and serve it in little tarts, which is also allowed.

Green's is better known in Britain for its baking mixes, so it tends to go in the basket with a sponge or cheesecake mix. A tin of custard powder and a packet of shortcrust are rarely far behind.
