What is one tip you learned about cooking that was simple but made a huge difference: Part 2 - Home Cooking
Kosher salt, in a dish, by the stove.
TASTE and season as you go.
Never use a dull knife.
Always preheat an oven.
Al dente pasta is the only way to go.
Use room temp eggs.
A separate freezer is a home cooks best friend.
Put a thin (3/8” to 1/2") steak in the freezer for 15 minutes or so before cooking will allow you to get a
nice sear on the outside without overcooking the middle. Works for tuna, too
A slower, longer rise results in a better tasting bread.
Allow meat to rest before carving
Fresh juice is better than bottled
Don't crowd food in a pan when browning
brewing a clove or two of garlic into the boiling pasta water
Zest has more flavor than juice
add seltzer water to the pancake mix for fluffiness
Separate the eggs and beat the whites for fluffier pancakes
flick water at the oiled griddle and it dances, it's the right temperature
WAIT till the pan gets hot
Brown meat for extra flavor then deglaze pan to capture the flavor of the fond in your sauce
Fresh herbs are far better than dried.
Use herbs toward end of cooking process (chefs say, "the last thing you add is the first thing you taste")
When making a sauce add cold liquid to hot ingredients for the sauce to be lump free
Pull your pasta when it's pre-al dente and finish cooking your pasta in the sauce
Baking bacon is better than frying
