Tupperware Police Don't Read This!!!
I don't like "Tupperware" containers to store food. I don't store that many leftovers so maybe that is why I have never gotten into the "Tupperware" thing. (We eat everything that is on our plates!) I have tried to use plastic storage containers. I just don't like how the food stains the plastic. The container always looks dirty even when it is brand new. I also struggle with finding storage for plastic storage containers. Have you ever noticed that plastic storage containers can never be stored organized? They can't be stacked properly or "stay put". I have a small kitchen so storage is a huge concern.
I do need to store food so I am always looking for solutions that work for me. I store my leftover food on a dinner plate or in a glass bowl with plastic wrap or wax paper over it. If the portion is a small enough, I place the food in a French jelly jar. I use these jelly jars for my beverage glasses so they don't require additional storage space. They are great to stack in the fridge and have red plastic lids that assist in storing the food airtight but also in keeping multiple jars stacked. I love the look of them and they are so practical. Glass is the way to go.
I recently found that the brand Ziploc makes reuseable plastic containers. They are called "Snap and Seal". These containers are great for sending food home with guests. I like the practical size of them. The plastic does not stain or hold odors. They are microwave safe. If you do find one needs replaced simply pop it into your recycling bin and start a fresh one. These containers come in a pack of five.
