Get a butter crock (one that you store in water) and you'll have perfect spreadable butter 24/7. Just change the water out every 2-3 days.
Some other tips I live by:
-It's OK to use Dish soap on cast iron. Modern soaps don't use lye which was the agent that caused issues before. But still season it every so often.
-Don't put oil in your pasta water, it just coats the noodle and makes it hard for sauces to cling to. 1000% salt the water though.
-Use 1/4 tsp of baking soda to reduce tomato sauce acidity. Perfect for chilis, soups, or anything else needing tomato sauce.
-Store your condiments in the pull out drawer of your fridge, and produce in the door. Honestly it's the best thing I've done with my food storage. You'll be more inclined to use them, sauces take up less fridge space, and the air circulation will be better for your produce to not get moldy and gross. I haven't had to throw away a moldy bag of lettuce since.
