Mister North and I must be very rare specimens indeed because we went to a primary school that served excellent school dinners. The only thing I remember hating was the cabbage which they served minced and overcooked. Otherwise, I have very fond memories of eating lunch at school. There were proper hand cut twice cooked chips that I still dream about, Irish stew and of course, proper puddings with custard to match.

Most people liked the chocolate sponge and custard best, but my favourite was the cornflake pudding. A slab of crumbly pastry topped with red jam and sweet crunchy cornflakes on top, served with simple yellow custard. I last ate it when I was no more than 11 years old and I’ve spent years trying to track a recipe for it down. I’ve asked many people if they remembered it and in between triggering memories of Spam fritters, people have either rhapsodised about it or looked blank.

I was starting to think it was a Northern Irish thing when eventually I came across something about on Mumsnet and realised it was actually very simple to make and just the thing to use up some spare pastry. But would it taste the same or was I about to destroy a treasured childhood memory like the time I rewatched Button Moon and realised it was just an actual button?

Cornflake Tarts (makes 4 individual sized tarts)

For the pastry:

• 175g plain flour
• 45g cold cubed butter
• 40g lard
• 2-3 tablespoons cold water

For the topping:

• 150g raspberry jam
• 30g unsalted butter
• 25g sugar
• 1 tablespoon golden syrup
• 75g cornflakes

Start by making your pastry. I like the incredible shortness you get using half lard and half butter (plus it’s much cheaper too) but if you prefer, you can use all butter.

Put the flour in a large bowl and rub the lard and butter through it. I think I’ve mentioned before that my pastry always shrinks massively in the tin and some plaintive wailing about it to a friend, established that I was rubbing my fat into the flour too much and over working the pastry. So don’t be afraid to leave some lumps of fat in this instead of trying to get only tiny crumbs.

Add two tablespoons of ice cold water (I’ve also been using too much water because overworking the pastry had made it dry) and bring it all together neatly in a ball without too much fiddling and poking. Chill it in the fridge for 30 minutes.

When you are ready, roll it out and line the tart tins. I had 4 small ones but this will also do a 23cm tart tin nicely. Don’t trim all the pastry off the edges, but leave some overhang and then chill again for 15-20 minutes while the oven heats up to 180ºC.

Line the pastry with greaseproof paper and fill it with rice or dried beans and blind bake for 12 minutes. In the meantime, heat together the butter, sugar and golden syrup in a saucepan until it is all melted and runny. Put the cornflakes in a large bowl and pour the butter and syrup over them. Gently stir it through until they are all coated. Set aside.

Now put the jam into the same saucepan and warm it through too. I used some homemade stuff, but a decent shop bought one will do. Try not to use indeterminate ‘red jam’ like the school dinner version did. It’s better with a bit of flavour and texture.

Take the blind baked tarts out of the oven. Remove the baking beans or rice and prick the base of the pastry several times with a fork. Trim the edges of the tarts with a sharp knife and then spread the warmed jam over all the base of the tarts. Sprinkle the cornflake mixture over the top of the jam, making sure you don’t skimp.

Bake the tarts for another 8 minutes and then allow to cool for at least 10 minutes to give the cornflakes a proper crunch. You’ll probably want to serve this with a generous pouring of custard. I can’t help you here as custard is my nemesis and my most recent attempt at heating some fresh stuff from Sainsbury’s ended with me curdling it!

I ate my tarts just as they were and they tasted exactly like I remember, but actually slightly better for not being made with marge and cheap jam or washed down with tepid water in a metal beaker! I am now convinced Proust was really on about cornflake tart rather than madeleines…

What about you? Do you have a school dinner memory that’s surprisingly good or was it all crimes against food?
