Thrifty cheesecake

This is a great way to use up bits and pieces from the fridge and larder to make a small dessert. I started making this after I froze a spare packet of cream cheese and when I defrosted much later, I discovered it had split. I hate throwing food away so had to think up ways to use it up. This makes enough for two individual cheesecakes - perfect for when you want something sweet but just a small taste of it.

What you need:

1/2 packet of soft cheese, such as Philadelphia 

A level dsp of icing sugar

1 tsp vanilla essence

1 tsp lemon essence

2-3 plain hobnobs or other biscuits

A small knob of butter

What to do:

Put the biscuits in a paper bag and crush them with a rolling pin. Melt the butter in a small bowl set over a pan of simmering water. Add the biscuit crumbs and mix well. Spoon the mixture into two small ramekins and press it down well to make a firm base. Pop the ramekins in the fridge. 

Put the cheese and sugar into a bowl and mix well. Taste to check the balance of flavours - you want to be able to taste the cheese and it shouldn't be too sweet. Add the two essences and mix well. Spoon it over the bases, pressing it in and smoothing the top, and put back in the fridge. Leave for a good hour to set firmly. 

Cook's tips:

How much biscuit and butter you need will depend on the size of your ramekins. I find2.5 is about right to make a base of about half a centimetre deep. You need just enough butter to coat the crumbs so they'll stick together, but not so much they set rock hard in the fridge - the base should hold together but still be crumble. About a teaspoon should be about right.

I use the bowl over hot water as the amount of butter is too small to melt directly in the pan and tends to just dissipate across the surface without coating the crumbs.

For a slightly posher version, omit the essences and substitute a little grated lemon zest and some seeds from a vanilla pod.

Instant banana ice cream

This cheat's ice cream is the best way I know to use up overripe bananas. It's not quite instant but it involves very little work, has only one ingredient and tastes amazing.

Ice cream is one of those things I always have in the freezer as I don't make puddings unless I have guests or some fruit to use up. It has to be premium ice cream for me and a small bowlful is plenty to satisfy any cravings I have for fat and sugar. Bananas have both without the need to add any extras and the simplicity of this does away with hours of making a custard base, churning and rechurning.You don't need an ice cream machine either, just a food processor.

I've been making this for so long that I have no idea where I originally discovered this. A friend who knows about such things explained the science to me - namely, that when bananas are frozen the fat they contain undergoes some kind of transformation and blitzing it produces the same creamy texture you get in proper ice cream. Whatever - it works!

What you need: 
4-6 very ripe bananas

What to do:
Peel the bananas and slice into 1cm rounds, discarding any blackened or badly bruised flesh. Spread the slices on a baking sheet and pop in the freezer for about an hour - they should be three-quarters frozen, not solid.

Put the three-quarters frozen banana slices into a food processor and blitz them until smooth. Put into a suitable container and refreeze. This makes about a pint / 1/2 litre depending on the size of the bananas.

Cook's tips: 
It's really important that you don't over-freeze the banana - blitzing it fully frozen could burn out the motor  in your food processor. If the slices have frozen solid, leave them to soften a bit before processing.

This freezes rock hard once blitzed and refrozen so take it out of the freezer for 10-15 minutes to soften slightly before scooping a portion.

Extras -  you can, of course, add extra ingredients once you've pulped the banana flesh. Things I've tried that work well include chocolate chips, dessicated coconut, chopped nuts (pistachios, brazils and walnuts are especially good), candied peel. and chopped glacé cherries. For an even creamier texture you could stir through some double cream or Greek yoghurt after processing. Beware of using crème fraiche as it can split when it thaws.

As far as I know this will keep indefinitely, although it's never lasted long enough for me to find out!
