I personally don’t make guac often, what I will do though is make pico de gallo with diced avacado and extra lime (to minimize browning). I will then place it on anything I’d put pico on - steaks, grilled or baked chicken, tacos, etc. I do plan on using it all in 48 hours, 72 MAX, and find that putting plastic wrap on top between uses -right down- in contact with the surfaces slows the browning enough to be manageable in that time frame.
Blending (with a fork or other tool) it down into a smooth or chunky place doesn’t work for me.
Caveat though - I only do this if I have decent ingredients for the rest. Fresh cilantro, serrano chiles (or fine diced habanero), fresh garden tomatoes, garlic, fresh onion, etc. The lowest quality ingredient can kill what would otherwise be tasty. And for commercial, store bought guac, it often does.
