Can You Put Hot Bacon Grease in a Glass Jar? A Complete Guide

After cooking up a tasty batch of bacon, you’re left with delicious rendered bacon fat. But what should you do with that liquid gold? It may be tempting to pour the hot grease directly into a glass jar for storage. However, this isn’t recommended.

In this article, we’ll cover whether it’s safe to put hot bacon grease in a glass jar, the potential risks, tips for safe storage, and how to use your saved bacon fat for flavorful cooking.

Is It Safe to Put Hot Bacon Grease in a Glass Jar?

The short answer is no – you should never pour hot bacon grease directly into a glass jar. The extreme temperature change from hot to room temperature can cause the glass to expand rapidly, potentially leading it to crack or shatter. This can result in a serious injury from the broken glass or hot grease.

Instead, it’s safest to let the bacon grease cool down significantly before transferring it to a glass jar for storage. Allow at least 30-60 minutes for the grease to come towards room temperature. Warm is fine, but you want to avoid grease that is still hot or even very warm.

Glass jars are not designed to withstand such rapid heating and cooling. Save yourself the mess and potential harm by waiting for that bacon grease to cool off first

Dangers of Putting Hot Grease in Glass

To understand why it’s unsafe to pour hot grease into glass, it helps to consider how glass reacts to extreme temperature changes:

  • Expansion – When glass is heated rapidly, it expands at a faster rate than the inner material can properly adjust. This mismatch in expansion can cause stress fractures.

  • Weakened structure – Exposing glass to thermal shock weakens its physical structure by putting stress on the molecular bonds. It becomes more prone to breaking.

  • Trapped steam – Any moisture or steam present when hot grease is added can also cause pressure buildup inside a tightly sealed jar. This increases the chances of an explosion.

  • Burn risk – Hot glass looks just like cold glass. The jar could easily be picked up with bare hands before cooling, leading to serious burns.

To avoid these risks, always let grease cool down significantly before adding to a glass jar. Never pour piping hot grease into glass containers.

Tips for Safe Bacon Grease Storage

To safely save that bacon grease for later use, follow these tips:

  • Use heat-safe tempered glass jars that can withstand extremes Or choose stainless steel or ceramic instead

  • Allow grease to cool on the counter for 30-60 minutes after cooking.

  • Strain out any bacon bits with a mesh sieve before transferring to the jar.

  • Fill the jar only halfway to allow for expansion as the grease cools and solidifies.

  • Seal the jar tightly before refrigerating. Freeze for longer storage.

  • Label the jar with the contents and date to track freshness.

  • Discard grease after 1 month (fridge) or 1 year (freezer) to prevent rancidity.

Following these guidelines will allow you to safely save that bacony goodness for future cooking adventures.

Creative Uses for Leftover Bacon Fat

Once you’ve safely stored your cooled bacon grease, how can you use it for flavorful cooking? Here are some delicious ideas:

  • Sauté vegetables like Brussels sprouts, green beans, potatoes etc. for a smoky essence.

  • Fry eggs in bacon grease for an extra savory morning meal.

  • Use as the fat for making roux in gumbos, stews, and gravies.

  • Brush on meats before grilling or roasting to keep them moist and infuse bacon flavor.

  • Add a spoonful when baking cornbread, biscuits, scones etc. for extra richness.

  • Toss with roasted root vegetables like carrots, parsnips, and potatoes.

  • Sizzle sliced new potatoes or home fries in it for breakfast or a side dish.

  • Flavor the oil for making homemade salad dressings and vinaigrettes.

With so many uses, you’ll be happy you safely stored that bacon fat for cooking later on!
