Silicone bakeware almost seems too good to be true. Reusable, non-stick, and available in hundreds of sizes, colors, and fun shapes, these tools and containers make baking even more creative and fun. They are also much less wasteful, reducing the need for paper cupcake wrappers and rolls upon rolls of parchment paper. Plus, silicon bakeware is easy to clean and durable enough to withstand years of use. 

But are there drawbacks — or even dangers — to regularly using silicone baking molds? Sure, these baking tools are popular and convenient, but are they really what you need? Let’s dive into the ins and outs of baking with silicone.

The 411 on silicone baking molds

While silicone is a synthetic type of rubber, its actual makeup includes oxygen, bonded silicon (which is abundant in sand and rock), carbon, plus a host of other chemicals to increase durability. Silicone is safe in the freezer, microwave, dishwasher, and oven (up to 428 degrees Fahrenheit), so it’s an extraordinarily convenient material. Sadly, it can’t be recycled, nor is it biodegradable, so although it isn’t as bad for the environment as single-use plastics, it’s not exactly the most eco-friendly option either. A bit temperamental, your silicone baking molds and cookware need to be completely dried prior to storing or they become prone to discoloration, stickiness, or other forms of deterioration.

These molds are a great solution for reducing fat in your baking since the 100% non-stick surface means you don’t have to spray them with oil or butter. While many bakers still choose to do so, it’s certainly not a necessity.

Like traditional baking tins and molds, you can have a lot of fun with silicone baking tools. Get your kids in the kitchen to bake sweet treats in the shapes of seasonal symbols, popular characters, hearts, stars, and more. And, once the muffins or cakes are done and cooled, they’re easy to pop out. This material also cools very quickly, so you don’t have to worry about your little ones burning their fingers.

Over time, your silicone bakeware may develop a greasy film that is difficult to remove, particularly if you use cooking spray. In this case, it’s best to pop it in the dishwasher for more vigorous cleaning. To get the job done yourself, hand wash the bakeware with a touch of baking soda to remove any lingering residue.

Is silicone bad for baking?

With all the pros covered, you may be wondering: Is silicone safe? There’s a lot of misinformation out there about the toxicity of this material, so you’ll be happy to know it’s 100% safe and nontoxic. Even lower-quality silicone is safe to use because it’s chemically stable. It just might not be as durable as others.

Much of the concern about the safety of this material has to do with its other uses that aren’t related to food. This is a very versatile material, so it finds itself in adhesives, electrical insulation, beauty products, and medical implants. So, while one form of the material, liquid silicone, may be safe for manufacturing parts, it should not be used for injections like lip fillers. Long story short, silicone comes in many forms, so be sure you’re only using the product for its intended purpose. Food-grade silicone is perfectly harmless for all of your baking needs.

Are silicone baking products worth it?

Now that we know this material is safe, it’s time to discuss whether it’s effective. The material of your baking tools has a large impact on the final result of your dishes, so keep in mind that food will cook differently on silicone than it would in tin pans. Cookies, for example, brown easily on this material because silicone conducts heat through the dough differently. Additionally, its nonstick surface makes the dough spread faster, bake quicker, and flatten more. Before you start baking, do a little research to determine what type of dish is best for your project.

Silicone is a safe, easy-to-use, and inexpensive baking tool that more and more cooks are embracing. Just like with any tool, there are benefits and drawbacks, so determine its usefulness on a case-by-case basis to make sure you nail the recipe every time.

We all love Costco samples, but doing these 6 things will make everyone hate you

There are a lot of reasons to love shopping at Costco — the prices, the breadth of products, the cheap food court — but the Costco samples are definitely at the top of the list. Who doesn’t love free, delicious food? Not only is it a great mid-shop snack, but it gives you the opportunity to try items before you buy in bulk.

Of course, the samples come with their problems, too — congested aisles, long lines, and poor etiquette. One Costco sampler recently took to the r/Costco subreddit to offer up some do’s and don’ts when checking out the Costco samples — and fellow workers and shoppers joined in.

While gas-powered vehicles are still the dominant best seller in the U.S., as much as 45% of new car sales are predicted to be made up of electric vehicles by 2035. The U.S. government has a more ambitious goal — 50% by 2030 — and has implemented a number of policies and plans aimed at increasing the sales of EVs. While electric vehicles are better for the planet — and, certainly, people are taking action to reduce their impact on the environment — the question remains: Just how much will eco-friendly vehicles impact the electricity bill each month?

Will homeowners end up spending more on their utility bill than they save on gas? Keep reading to learn the answers to these questions and so many more.
