I love cooking, and I cook every day for me and my wife (home office since 2008 helps there), and I love hearing about new things. I have the book “The Science of Cooking” which was fascinating.
Microwave or parboil veggies before sauteing on high heat. Lets you get the perfect exterior without having to worry about if they are cooked through. It’s also faster and if you parboil in salted water you allow salt to penetrate deeper into the veg. I especially like this technique for starches like potatoes, as they take a long time to cook and I’m impatient.
