There are a select few products that all food/kitchen people must have. These are the products everyone needs, not just the foodie/top chef/food network fanatics!
For most people, it’s a no brainer that they need a good blender. For others, it might not be so obvious. Blenders are the best all in one tool for any kitchen. You can get away with not having lots of products if you have a good blender.
Honestly, you are not going to find much differences among crock pots. Just make sure to get at least a 6 quart crock pot and you are good to go for all the slow cooked meals you always wanted to make.
