Rhubarb Turkish Delight

You are so lucky that rhubarb season is coming to an end.  I am sure you have seen more of rhubarb than you ever thought possible!  I have been having fun with it.

I have adapted a recipe from The British Larder.  If you have not been on her website, you really must.  She is a truly inspired chef and is opening her very own restaurant in Suffolk, England soon.

I love this sweet!  It turned out a little softer than I would like but I was too afraid to overcook the mixture.  I know the recipe says to boil until it reaches 112C.  After taking candy and chocolate making classes from Jean Pierre Wybauw, I know that it isn't all about temperature.  I would love to find a recipe, or perhaps adapt this recipe, so I can use the refractometer to measure the doneness of the sugar syrup.

I would prefer to err on the side of softness rather than hardness when it comes to a delicate sweet like this.  I will definitely be making this again!  I used my rhubarb simple syrup and it was perfect.

When I was studying home economics at university, I learned that if a gelatin is allowed to set at a higher temperature (say room temperature) rather than a lower temperature (such as the refrigerator), the resultant jelly would be firmer and maintain that firmness better at room temperature.  Hence, the suggestion not to let this set in the refrigerator.  See Cooks Notes below.

Rhubarb Turkish Delight                     adapted from The British Larder

2 cups of rhubarb simple syrup
1 envelope of gelatin powder
2 tablespoons of cornstarch
1/4 + 1/4 cup of water
2 tablespoons of cornstarch and 4 tablespoons of icing sugar

Line the bottom and sides of a standard loaf pan with plastic wrap.  Sift the cornstarch with the icing sugar and set aside.

Soften the gelatin powder in 1/4 cup of warm water.  Let it bloom until fully hydrated.  At the same time, dissolve the cornstarch in 1/4 cup of cold water.  Mix to make a slurry.

Put the rhubarb simple syrup in a non-reactive pot.  Add the softened gelatin and the cornstarch mixture.  Stir to blend completely.

Heat over medium high heat for about 15 - 20 minutes, approximately 112C.

Remove from the heat and cool slightly.  Then pour into the prepared pan.  Let sit 12 hours at room temperature.  Do not refrigerate.

Remove the jellied mixture from the pan and place on a cutting board that has been liberally dusted with the cornstarch and icing sugar mixture.  Dust the top of the jellied mixture, as well.  With a clean, sharp knife cut into desired shapes and sizes.  Carefully toss the jellied candy in the cornstarch and icing sugar mixture.  Place on parchment paper to dry.

Do not store in the refrigerator.  Store in a tightly closed container in a cold room.  This will keep up to 3 months.

Cooks Notes:
Temperature. With a definite concentration and time for setting, solidification occurs only with a definite temperature. For a high solidifying temperature a high concentration of gelatin is required. The slower a gelatin solution is cooled, the higher the temperature at which it solidifies. A gelatin solution may be cooled down, by packing ice around its container, to a temperature below that at which setting would occur if a longer time is allowed. On the other hand, gelatin solutions may be mixed and left standing for 2 or 3 hours at room temperature. If they are then put in ice or the refrigerator they set quite rapidly and as if gel nuclei might have started to form while standing at room temperature. At low temperatures all gelatins become firmer. At high temperatures they are liquid, for no gel occurs at temperatures above 35°C. with any concentration of gelatin. With the same concentration one gel may set at 10°C, another at 12°, still another at 14° to 16°C, and others require lower temperatures for setting. The gelatins that set at higher temperatures show jellies of greater firmness than those that set at low temperatures. The ones requiring lower temperatures than 10°C. to set do not serve very well, for they also soften at a low temperature.

  2. Such a pretty pink color! This sounds like an easy recipe that my daughter would love to be involved in. thanks for the helpful tips on gelatin setting up, I had no idea that its firmness was affected by temperature! I love your blog Sarah, I always learn something new :) Thank you for that!!

  3. Hungry> that's an idea! Never thought of it.

    Andrea> thank you! I would be careful whilst boiling the sugar syrup but a little one could absolutely help with tossing them in the powdered sugar at the end.

  4. I shall remember the higher temp setting pointer! I've not made many gelatins just because they don't hold up well at serving. Your rhubarb confections have been pretty, and sound delicious!

    I am impressed; your rahet halkoum as we call it here is very pro looking; bet it tastes wonderful rather than the sweet stuff we buy! Great info on the gelatin. I am trying to switch to agar-agar though these days.

  8. i've never heard of a home cook using a refractometer--that's something i use at work in the science lab all the time! gorgeous treat, sarah. :)

    1. The package has metric in volume rather than weight. It says 15 mL of gelatine.
