Sea Glass Candy

Hard candy is easy to make, and it’s one of those things that everybody should try at least once. This simple process is used for everything from lollipops to cough drops, and it’s kind of nice to know how it’s done. The base is a mix of water, sugar, and corn syrup. You add a drop or two of regular food coloring, and a drop of food grade flavor oil. It gets heated to 300F, or what is known as the ‘hard crack’ stage of candy making. This just means it’s the temperature where the candy cools to the hard candy texture. A lower temperature will result in softer or stickier candy.

Making Sea Glass Candy

The molten sugar mixture is immediately poured out onto a greased surface to cool.

Once hard, it can be shattered into shards, just like glass!

I have to say I was astounded at how ‘glass-like’ this candy was — it’s sharp! I’m sure there’s science behind it, the sugar crystals must be similar in some ways to the grains of sand that melt into actual glass. Anyway, it’s easy, fascinating, and fun. Probably not for real little ones, but teens might enjoy this.

The next step is also fun — you’ll coat the bits of ‘glass’ with powdered sugar, and they’ll emerge looking exactly like sea glass!

I used a dish cloth to buff off the excess sugar and ‘sand’ down the sharp edges for an authentic look. And you’re left with a big batch of hard candy that looks like you just collected it off the beach. What to do with it? Well, that’s where your creativity comes in, you can throw an Endless Summer themed party, (or wedding!) give it as a gift, or just pat yourself on the back for a crossing another culinary feat off your bucket list.

I made only one color but you could play around with all kinds of shades of greens and blues, just like the real thing. Tie them up in little cello bags for favors, or just put out in a candy dish. Remember that hard candy of any kind has a tendency to get sticky in humid weather, so just be aware. I would keep it in an airtight container and plan to use it up fairly  quickly.

Ingredients

  • 1 3/4 cup granulated sugar
  • 1/2 cup corn syrup
  • 1/2 cup water
  • 1 or 2 drops food coloring blues and greens work well
  • about 1/4 tsp or a few drops, of candy flavoring or food grade flavor oil (I used tangerine)
  • 1 cup powdered sugar for coating

Instructions

  • Lightly spray a 12 inch pizza pan
  • Put the granulated sugar, corn syrup, and water in a saucepan. Clip your candy thermometer to the side of the pan.
  • Bring up to a boil, while stirring to dissolve the sugar. Once boiling, stop stirring and let it bubble away until it reaches 300F on the thermometer. As it gets close to 300F, add in the drops of food coloring, but don't stir, it will mix itself in.
  • When it reaches 300F take it off the heat, stir in the flavoring oil, and immediately pour out onto your surface. It will spread out by itself. Be VERY CAREFUL, it is very hot.
  • Let the candy sit until fully cooled and hardened, then lay a piece of plastic wrap lightly over the surface and rap it with a hammer to shatter the candy into pieces. Do this slowly so you can try to get the most realistic size for your pieces.
  • Working in batches, put the pieces of candy into the powdered sugar and coat well. Use a dish towel to rub off the excess sugar and rub down the very sharp edges.
  • Store the candy in an airtight container, or divide up into individual cellophane bags.

Cook's notes

recipe from hp.com
The nutritional information for recipes on this site is provided as a courtesy and although theviewfromgreatisland.com tries to provide accurate nutritional information, these figures are only estimates.

tips:

  • You’re going to need a candy thermometer for this. You should have one anyway, they are a necessity for most types of candy making, an deep frying, too.
  • Look for candy flavoring oils in the baking aisle of your supermarket, you might find one or two there. Otherwise, for a wider choice, visit a large craft store like Michael’s, or go online. There are endless choices, from root beer to pina colada.
  • Be very careful when working with molten sugar. It is dangerously hot and you don’t want to touch it. Keep away from children and pets.
  • I found that for this recipe my 12″ metal pizza pan worked perfectly. The mixture will spread too thinly if you use a very large surface.

    I’d never made hard candy before and this was way easier than I expected!! Thank you for the easy to follow recipe! I’m making wedding favors for my mom’s wedding so I thought these would be ADORABLE, as the whole wedding theme revolves around sea glass. I was hoping to make them more tart, though. I’ll test it out by adding some citric acid and perhaps follow up on my measurements if it works out well! Thank you again!

    What color combo did you use to make this candy color? What was the ratio of blue to green?

    This is my first time trying this recipe. Yours look awesome. How long does it take to harden? I’ve had mine drying for a few hours now and they’re taking forever. I used light corn syrup, could that be the problem?

      Is it possible you didn’t heat the mixture all the way to 300F Tiffany? That temperature is essential for the candy to get to the ‘hard crack’ stage, where it hardens as it should.

    In case nobody else has beaten me to it: DO NOT USE ESSENTIAL OILS FOR FLAVORING. DO NOT CONSUME ESSENTIAL OILS, OR TAKE THEM INTERNALLY FOR ANY REASON.
    It can, among other risks, completely destroy your kidneys. Unless a shortened lifetime of pain and dialysis treatments sounds fun to you, stick to flavoring oils that are meant to be consumed.
