Sea Glass Candy Recipe

diy wedding favors

I recently made my own sea glass candy. Yum! To be honest, this was my first attempt EVER at making candy – and it was a breeze!

These candies aren’t only easy – they’re super tasty too. My husband and kids gobbled down the rootbeer candies so fast I didn’t even have time place them inside a favor tin to snap a photo!

These would be perfect to give as gifts.

Sea Glass Candy Recipe


  • 2 cups granulated sugar
  • 3/4 cup water
  • 3/4 cup corn syrup
  • 1/4 – 1 tsp. flavoring oil (I used raspberry and rootbeer but you can use any flavor you want!)
  • Icing sugar (to coat cooled candy)
  • edible diy wedding favors

    Step One

    Grease a cookie sheet or cake pan with butter.

    Step Two

    Measure ingredients.

    Step Three

    Pour granulated sugar, corn syrup and water in a medium saucepan. Place over medium heat and stir until sugar dissolves.

    Step Four

    Without stirring, boil the mixture until a candy thermometer reads between 300 and 310 degrees. (This will take about 30 minutes.) Drop a small amount into ice water. If it separates into brittle strands its ready.

    Step Five

    Remove from heat and let boiling subside.

    Step Six

    Measure flavoring oil and pour into candy mixture. Also add food coloring if desired. Blend with a wooden spoon. (You’ll notice that it will get really steamy for a few seconds.)

    Step Ten

    If giving as gifts, place into favor tins. (I lined the inside with a cupcake liner.) Tie with ribbon and adhere labels.

    Lovely! I make all kinds of candy & never came across this. I’m going to give it a try. What a great gift idea. Thanks for posting!

    they look sow amazing i’ll to make them

    […] and she delightfully recounts how she she fell in love with sea glass! She even has a recipe for Sea Glass Candy! I told her of a huge jug of sea glass that I inherited from my mother-in-law Gail and she warned […]

    Can anyone tell me how to achieve the rounded edges of the sea rocks candy?

    Hi Theresa,

    Not sure how you would make them look round.

    I made these last night, passion fruit flavoured, and I am amazed at how easy this really is. Even my kids helped with the final dusting (and eating) process. Great recipe!!!

    Love this! I am making it for my beach wedding, however, I don’t know how to make it white. I am using light corn syrup but after cooking it still has a yellow tint, any suggestions?

    Not sure how you would make these white. Even if you use white corn syrup, it will turn golden as it cooks.

    Anyone know how to keep this yummy candy from ‘melting’ in the container in the hot weather?!!

    I just made this for my aunt’s wedding favors. When I tried water for rounding edges it was too sticky. Microwave only heated the middle. So I went out on the deck in the sun, and bingo! The edges softened up nicely with a little pressure on them, and oncevinside it reset perfectly. I did use a Silpat for half the batch, which gave it a burlap texture. I didn’t Luke it at first. But then I noticed it caught the light in pretty way. Also looks a lot more like bottle glass this way.

    These look great! Have you ever tried making shapes such as a heart? I am doing cupcakes for a wedding and would like to do a “glass” heart for the top, however I’m not very experienced with this sort of candy.

    Hi Krystle. No I haven’t tried any other shapes. It would be fun to experiment though!

    Great tip!

    Im going to make it but i dont have any corn syrup. can i use pancake syrup instead

    My grandmother and aunt used to make this candy when I was a child. Usually at Christmas time, flavoring it with cinnamon and spearment and coloring them red and green! It was so wonderful!
    They saved baby food jars all year long and used them to store the candy in and to use in gift giving with ribbons tied so lovingly. Memories!

    haven’t tried this but,how about using cookie cutters for different shapes. greasing them of course .size of your choice.

    I haven’t tried this, but if you do, let me know Jennifer!

    Thanks for your comment Sandy. How sweet!

    I saw these and love them! I’m getting married in June – once they’re made, about how long can they be stored? Also – has anyone made them in white, tanish, or pinks? Any tips would be great! Thanks!

    @jackie – If you use light corn syrup it might not get quite so caramelized AND they do make white food coloring…that might get you to something close to a an off-white.

    LOVE this! Going to make this for a First Communion treat for a special little girl that loves sea glass! This may seem like a silly question – but what exactly are flavoring oils and where can I get them? Is this the same as flavoring “extracts” that I can find at the grocery store?

    I’m going to make this for my daughter’s beach/pool party for her birthday. Thanks for sharing. As for making shapes, try a silicone mold. I’ll be trying that to make star fish.

    Joy just wanted to tell you
    That you really want to use an oil flavoring,they work so much better then the kind you get from the grocery store,try a craft store and look for lorAnn flavoring

    When I still lived in RI, a very dear friend of mine & I would get together every year and make a lot of items for gift baskets, we did a lot of canning, making tea breads, jellies, jams, etc. But the most favorite item was what we called Beach Glass Candy and I am not exaggerating when I tell you we took an ENTIRE DAY and would make SIXTY POUNDS of this candy in all different flavors!!! I still have the container we would mix all the flavors in. It is very precious to me. It is what is called an Ancient Chinese Egg Bowl, where the Chinese preserve these eggs in some manner. Well my friend and her husband, Frank gave it to me one year for my birthday, but it took a lot of talking from Frank to the owner of the Chinese Market to buy it, b/c they are very difficult to come by. Frank passed away several years ago from cancer! I have had this bowl for over 25 years & it will always be a treasure to me!

    OH and we used to set up the disposable metal casseroles filled with confectioner’s sugar & pour the hot mixture into it, then we would break it up. The only one we didn’t combine in the big bowl was the homemade butterscotch.
