Here's a recipe for homemade salt candy that helps prevent heatstroke. It's a simple process: just heat salt, sugar, and water in a pot, pour it into a mold, and let it harden. The key is to just watch it without stirring while it's heating, as stirring will cause it to crystallize. Turn off the heat as soon as it turns yellow to prevent burning. You can use aluminum cups or silicone molds from Daiso to make a perfect summer snack to enjoy at work or during club activities.
