It seems there may be a misunderstanding in your request. The product you're referring to, the "Coool-it Silicone Adapter for Tall Slim Cans Compatible With Yeti Type Stainless Can Coolers," is a silicone accessory designed to fit specific types of cans and coolers, not a food or beverage item. As such, it cannot be recreated as a homemade recipe using food ingredients.

If you're looking to create a homemade version of a silicone adapter, it's important to note that silicone products are typically made from synthetic materials like silicone rubber, which are not edible or replicable with common household ingredients. These products are manufactured using specialized materials and processes that are not feasible in a home kitchen.

If you're interested in creating a homemade solution to keep your beverages cold, there are other creative and edible ways to achieve that! For example, you could make homemade ice packs using water and freezer-safe bags, or even create flavored ice cubes to keep your drinks cold while adding a bit of extra flavor.
