No fruits are in season up here yet. I have some red currants in the freezer from last year, but some of that is destined for jelly which hasn't yet been made. I'd have to use either frozen or imported fruit for this challenge, or winter storage apples or pears. Then I found the following strawberry recipe and my choice was made.
Isinglass is a gelatin thickener made from fish swim bladders. I think you can still get it at some brewing supply stores, but not available locally, so I substituted regular, granulated gelatin which is available at our bulk food store quite inexpensively. A bit of research showed that I would need 1 tablespoon of gelatin for every 2 cups of liquid to get the liquid to form jelly and if I wanted to mould it I would need at least 25% more. Remember that gelatin needs to be soaked in cold water to "bloom" before it is dissolved in hot liquid.
I used 5 tablespoons of gelatin and sprinkled it over 3 cups of cold water to bloom. I then made a simple syrup of 2 1/4 cups water and 1 1/4 cup sugar. Making the syrup is the easiest way I know of making sure the sugar is completely dissolved. When it had cooled just a little bit, I added the soaked gelatin mixture and stirred until it was mixed in. Then I stirred in 3/4 cup freshly squeezed lemon juice which had been strained through a very fine mesh strainer to remove any pulp, seeds or unwanted bits.
The mould needs to set until completely firm. I left it overnight in the fridge to firm up and unmoulded it for lunch the next day. I could tell from the wobbly jelly, that it needed either a little more time to set up, or a little more gelatin in the liquid mixture.
I'd hoped the jelly would slice nicely for presentation purposes, but the bottom didn't have enough structural integrity to hold together. More gelatin next time, but also, I think the chopped strawberries changed up the fruit to gelatin ratio as well.
Despite the way the jelly collapased, it was really, really good. Good enough that I would do this again and again. It looked pretty spectacular before I cut into it.
Time - 1/2 hour to start, plus a few minutes here and there for the layers, plus overnight to set
Cost - $7.50 - Two packets of berries $5, gelatin $1, lemons 3/$1.50
Accuracy - except for the gelatin substitution and the fridge, pretty good.
Love it! It came out perfect!
ReplyDeletelooks great - maybe also as a dessert for a feast, with a few pieces of shortbread? pity, I'd have to eat it all myself, because jelly like this isn't for the guys in the house:(
ReplyDeleteand I agree with the last post - icelandic isn't really my fibre for spinning either. and I need to do some real spinning again, after just plying commercial cotton threads on the wheel for ages.... now I know why people like to use e-spinners for that sort of work:)
I love gelatin desserts!
ReplyDeleteAlso, on a previous challenge, one of the contestants discovered that modern powdered isinglass is cut with citric acid -- because that's how brewers need it, and thus it doesn't work at the listed ratios. So gelatin is the way to go!
