What kitchen utensils did not exist 50 years ago?

Here are some kitchen utensils that did not exist 50 years ago (circa 1973):

Technology-Driven:

* Immersion Blenders: While blenders existed, the immersion blender, which allows you to blend directly in a pot or bowl, was a relatively new invention.

* Food Processors: These powerful machines that chop, slice, dice, and more were just beginning to gain popularity.

* Electric Kettle: While kettles were common, electric kettles that rapidly boiled water were not widespread.

* Air Fryers: The concept of "air frying" didn't exist.

* Instant Pot: Multi-function pressure cookers with added features like slow cooking and yogurt making weren't available.

* Sous Vide Circulators: Precise temperature control for cooking was a niche, professional application.

Specialized Tools:

* Spiralizers: These tools for creating vegetable noodles weren't common.

* Avocado Slicers: Dedicated tools for safely and easily cutting avocados were not widespread.

* Silicone Spatulas: Flexible, heat-resistant spatulas made of silicone were relatively new.

* Microplane Zesters: This type of grater, with its fine blades, was not commonly found in home kitchens.

* Mandoline Slicers: These tools for creating uniform slices were mostly used by professional chefs.

Other:

* Reusable Food Wraps: Alternatives to plastic wrap, like beeswax wraps, were not common.

* Silicone Baking Mats: Non-stick baking sheets made of silicone were not widespread.

Important Note: Some of these items might have existed in limited forms or in specialized contexts, but they weren't widely available to home cooks in 1973.
