Isomalt is a beautfiul thing. It is one of my favorite mediums because of the unique and often realistic look it can bring to a cake. We find that many people are intimidated by isomalt and we are here to ease any apprehension! Once you start working with it and see what it can do you will kick yourself for waiting so long.

Our first tip for working with isomalt is buying it Ready-To-Use from Simi Cakes & Confections! Their ready to use isomalt can be popped in the microwave in 20-30 second intervals and boom it is ready to pour, pull or cast! SO convenient. Simi Cakes isomalt is exceptionally clear and definitely affordable. One of the best things about isomalt is there is never any waste so you really get your money’s worth.

Using silicone molds to make crowns, brooches and many other decorative elements is one of the easiest and most fun ways to use isomalt. Always use heat proof silicone containers for pouring isomalt and wear protective gloves! The gloves’ main function is to protect you from the dangers of the heat but they also keep you from getting fingerprints on your beautiful shiny isomalt piece!

Both molds shown are from Marvelous Molds and they have a huge array of fabulous silicone molds perfect for making isomalt pieces!

Having a creme brule torch is a vital part to working with isomalt. If you happen to get a fingerprint on your isomalt, torch it. If the isomalt looks cloudy after coming out of a mold, torch it. If you have a little crack, torch it. Need to stick two pieces together? Torch it. You get the idea.

If you fancy cooking your own isomalt at home, you can also buy the raw isomalt crystals from Simi Cakes. Check out the video below on how to do it! Once cooled you can store any unused isomalt in a ziploc bag or airtight container indefinitely. To completely seal an isomalt piece spray it with PME Edible Glaze Spray. For cake show or competition pieces ONLY you can actually spray your isomalt pieces with actual clear coat from a hardware store. If the cake is to actually be consumed though you must use the edible spray. No poisoning your clients guys, no bueno.

Recipe Notes

Use extreme caution when making isomalt! Wear latex gloves and have a bowl of ice water in your work area ready for any accidents. Isomalt can cause 1st, 2nd and 3rd degree burns if touched to skin while hot. Hot isomalt will stick to your skin, so make sure you have the gloves on before you start working. In the event of getting isomalt on your hands, quickly peel off the gloves and put your hands in the ice water to cool the affected area. Continue to keep your hands in the water for at least 5 minutes. Call your doctor and get medical advice immediately.
