FEATURED RECIPE

A Hard Tack Family Tradition

Hard tack candy also known as rock candy or stained glass candy. Making the candy is a tradition for many families like the Ganster's of Pittsburgh. In my family my grandmother would make this at Christmas for our family.

When my grandmother would make it she would make this on the stove top. Once it came to temperature should would gently pour it out onto a greased cookie sheets and then cut the candy with scissors. My mom and aunts all remember the day they would make this Christmas candy each year.

What equipment do I need?

I can't stress enough how important it is to make sure all your equipment and ingredients are ready prior to starting this process. Once the candy reaches temperature everything moves very quickly. You need the below.

  • Candy molds or baking sheets, both sprayed with cooking spray
  • Measuring spoons
  • Baking sheets
  • Baking rack
  • Mesh strainer
  • Pizza cutter, if not using molds
  • ThermoWorks ThermoPop or candy thermometer
all utensils needed for hard tack candy making

What ingredients do I need?

I used Lorann Oils which can be ordered in variety packs, or you choose the flavor packs. These essential cooking oils have been around since the 1960's, and pack quite a punch of flavor. So you will need the below ingredients for this recipe.

  • Sugar
  • Light Karo Syrup
  • Water
  • Food coloring
  • Lorann oils
  • Powdered sugar

Making the candy

I tested this recipe in both a 3-Quart Instant Pot Duo and a 6-Quart Instant Pot Duo. The 6-quart takes a few minutes longer than the 3-quart to make each batch but not much. Combine the sugar, Karo syrup, and water in your pressure cooker. Set the Instant Pot to Saute (normal) setting.

Note you can make this on the stove top using these directions, but it will take considerably longer.

You want to cook until the mixture comes to 280-degrees. Once the mixture starts to boil it will take about 7 minutes to come to 230-degrees. After that keep a close eye on your temperature as it will take about 20 minutes to come to 280-degrees.

Once the mixture reaches temperature you will need to work quickly. Turn off the Instant Pot. Add the oil and food dye. A word of warning, do not lean over the pot as the oils are strong and may clear your sinuses. I learned this one the hard way! LOL

Gently pour the candy mixture into the prepared mold which should be sitting on a cooling rack. Start in the middle and work your way out. Use the back of your spoon to smooth and help fill in.

Helpful hint: Once you have emptied your Instant Pot liner immediately soak it and your spoon in soapy water. Clean up can be difficult, however, warm water will dissolve any hardened candy from your utensils.

If using a baking sheet, use the spoon to make the single layer as uniform as possible. Working quickly use the pizza cutter to cut into pieces.

Once the candy is completely cooled remove from mold and break apart on the baking sheet. Cover in aluminum foil to help with easy clean up.

Put the candy into the mesh strainer, add the powdered sugar, and shake to cover the pieces completely. Do not put this step off to later or you will get stuck with sticky candy. 😉

Store in plastic bags or an airtight container for up to several weeks. These make great gifts for any holiday, or you can serve them at your next family get together, potluck, or party! Have your littles arrange the pieces into pretty mosaic patterns for a fun activity.

  1. This is a fond memory of mine, also. Many, many years ago (45 probably) my 1st Husband's Grandmother would always purchase this from a local church. However, theirs were thin shards, like it had been dropped and shattered when it was cool. Thanks for sharing...

    1. That's a great memory! If you pour onto a cookie sheet and cut with scissors you will get those shards you remember so fondly. Thanks for sharing! 🙂
