In the yellow corner we have
Hartley's lemon flavour jelly.
40p a packet at Sainsbury's
In the other yellow corner we have home made lemon jelly
Needs a few more ingredients than the Hartley's and a bit more equipment, oh it costs more too, about £1:60 for the amount of ingredients used.
The packet jelly goes in the jug with 100ml of water and into the microwave for a minute, the water & molten jelly don't really mix, so when you make it upto 500ml (or a UK pint) you have to stir it a fair bit to get an even mixture. Then you pour it into your moulds and put it in the fridge, total time ?About 4 minutes. Over in the real jelly corner the first job is a simple sugar syrup. 125ml of boiling water gets 125g of sugar dumped in and stirred till its all dissolved. Actually I let it stand and stirred in between my juicings. The sharp eyed amongst you will have spotted an orange, this has 2 uses. 1 it dilutes the citric acid from the lemons.
Second it improves the colour, giving you a strong yellow, rather than a vaguely murky translucence. That's the jelly liquid on the left ready for actual jelling. First of cut up 5 leaves of good gelatin and then just cover them with your jelly liquid. They are going to sit there softening for about 10mins. Whilst that's happening bring a pan of water upto simmer. The bowl with the softened gelatine is going to sit on that till all the jelly dissolves (another 10 mins) once that is done stir in the rest of the liquid. Pour through a sieve and or a strainer into your moulds and put it into the fridge. All the hard work is now done, spend the next few hours doing other things and not frequently going in the fridge to see how your Jellies are doing.
At this point I think its worth pointing out that the Hartley's jelly uses no artificial flavourings or colourings. Look at the packet closely and you'll see its lemon flavoured jelly. It doesn't use any lemons either. The citric acid might come from them I guess and the coyly named "natural flavourings" may use lemon oils, but the colour comes from beta-carotene and curcumin, thats carrots & tumeric to us. Here are the end results.
That's Hartley's on the left, and mine on the right. They are obviously quite different looking, fortunately a brave volunteer offered to do a blind tasting.
It probably comes as no surprise that the packet jelly didn't fare to well, at first it appeared to have a more subtle flavour than the home made jelly. On a second tasting this was declared to be a lack of flavour. The home made jelly packs a hefty citrus punch and has a much longer finish (and greater depth). Pretty much all my taste testers preferred the home made one. I'm not bothered by the fact its 4x dearer or that it takes about 10x as long to make, it is a glorious lemony summer dessert.
An occasional journal of food & drink, mostly the stuff I've made myself. There will of course be lots of cocktails

The well tempered gourmand
Oh dear a punning title and warning of a glut of edits.
Anyway this is about chocolate. Hard as it maybe to believe chocolate is pretty complicated stuff, it exists in 6 different crystal forms. The one we really want is the β crystal and to get that we have to temper the chocolate.
Normally chocolate already comes in this form, by melting it we mess that up, this is where tempering comes in. The old fashioned method involves heating the chocolate till its fully melted and up around a temperature of 41c. Then removing 3/4 and working that on a cool marble slab down to 28c then adding that to the remaining 1/4 and bringing it to a temperature of 31c.
However we can take advantage of a bit of science and do this in a slightly easier way, using seed crystals. Since our chocolate is already tempered,we can reserve a bit and use its crystals to get the melted chocolate to behave. A bit of reading suggests about 10% is enough. So put the remaining 90% in your double boiler and melt it, stirring to bring the whole lot to a uniform temperature of 41c. Take it off the heat, and drop in the reserved chocolate, stir till the whole lot is at 32c, the chocolate ought to be tempered. Its then time to use the chocolate, of course if it goes above 32c you'll have to temper again.
You should end up with a glossy chocolate that snaps very definitely. It is a bit of fuss, but it does provide a much better chocolate for some applications.

Apple pie
I've always loved apple pie, prefereably the really tart kind to lurk under sweet custard. My nan usually made it on a blue & white enemal pie plate (just like this) I'm very happy to have one of my own, but due to a packed table I had to use a bigger dish.
Now I never realised that the filling needed a recipe, its just apple & sugar, maybe some spice if you are being fancy, chuck it on a low light & wait till its done. then stuff that on your pastry lined plate and bung a pastry lid on top.
What I needed was a good sweet pastry recipe, Jamie Oliver came up with the goods first so away I went (I made it in a mixing bowl, other wise flour seems to go everywhere). Both him & Heston Blumenthal advocate rolling the pastry out between 2 sheets of greaseproof paper, that's good enough for me (and less flour to go all over). I made the classic mistake of not making the lid quite large enough, so there was an ugly patch .
This is it just out of the oven, unfortunately the timing of things meant that we couldn't cut & eat it straightaway, so it got served up a la modé. Which although not my favourite way to eat apple pie is good enough. Next time though it's custard for sure, the proper stuff made from powder out of a red,blue, and yellow tin (*)
(*) Yes I'm perfectly aware that this isn't proper custard, thank you, however proper custard isn't pyrophyrric or none newtonian. It's not just a kitchen it's a place for SCIENCE
