Yep, I start a "30 minute" recipe and 30 minutes later I've only now gotten the ingredients out of the fridge/spice drawer/cupboard and prepared as per the ingredients list.
To be fair, the "30 minutes" assumes that all the prep work is already done and that all you're doing is following the recipe from there.
Which is understandable, but not everything can be prepped far in advance. (Ok, maybe most can, but I just don't like looking at oxidized avocado and apple chunks.)
