2% milk, Lactaid and/or coconut/almond milk, flavored creamer, iced tea, eggs, leftovers, every imaginable condiment that comes in a bottle (my hubby is a "Jar Of This, Jar of That" guy), butter, mayo, ginger ale, carrot juice, ....that's the good stuff.
Then there's always produce in various stages of freshness or rottenness
one pickle left in the jar
1/2 cup of soup shoved and forgotten in the way back corners
stale bread and heels
and a partridge in a pear tree!
