Hello from sunny California.
Just a little citrus sharing:

my typical citrus haul in winter
blood oranges that are deep purple-red, pinkish orange cara caras, tangy sweet melo golds, sweet and mildly sour and bitter oro blancos, ecstatic sweet lemons, pink pomelos, weird kaffir-like lemons, and trusty navels.

A little sharing about sweet lemons, which are good for the stomach and fight colds. By the way, the acidity is very low:

Thanks for the info. I wonder why we never get some of those varieties in the Midwest. Specifically kafir lemons, oro blancos...

Tonight (no conscience influence from this OP) I was at Trader Joe's and bought a bag of heirloom navel oranges. If you ever seen them, you gotta try them! I have never been all that gung-ho about navel oranges but these are so flavorful. Not dry like navels can be. Delish.
