Can you use plastic chocolate molds to make toffee molds?

It is possible to use plastic chocolate molds to make toffee if the molds are made from a high-quality, food-grade plastic that is specifically designed to withstand high temperatures. However, it is important to note that toffee is a high-temperature candy and can reach temperatures of up to 300 degrees Fahrenheit (150 degrees Celsius). Some plastic chocolate molds may not be able to withstand such high temperatures and could melt or release harmful fumes.

Therefore, it is essential to ensure that the plastic chocolate molds you intend to use for making toffee are explicitly rated as safe for high-temperature applications. It is also advisable to follow the manufacturer's instructions for using the molds and to avoid exceeding the recommended temperature limits.

As an alternative, you can consider using metal chocolate molds or silicone candy molds that are specifically designed for making toffee. These types of molds are typically more durable and better suited for high-temperature candies like toffee.
