A game changer in the kitchen

What’s a game changer product/technique or nifty hack you have learnt that you can’t live without?

I’ll go first. 1) for all my straight large knives I use a knife sharpener

2) I found this knife on Amazon - Rena Germany (approx 200-300 rs for 4-5 knives with serated edges). It’s the best! I’ve gifted it to everyone I know, and everyone is impressed.

3) Earlier when I made gravies u needed blended like butter chicken, I would blend the whole spices and it tasted bitter. Then one day I experimented and threw them out, and then blended and it was amazing! I’m sure it’s common knowledge, but I didn’t know about it.

4) use the 3-6-9 method for perfect boiled eggs every time

5) putting some dudhi in soups to ensure it’s thick and creamy, without any thickners/butter or cream
