Spouse and I have a discussion on what to do after you pour a sauce out of a glass bottle. I do nothing but my wife takes her finger and wipes the excess from the bottle before she puts the lid back on. I think touching the food is disgusting and she thinks leaving it there to gum up the lid is disgusting. What do people do?
Same. The mess-less pour makes it a moot point.
I think OP’s no wipe leads to a messy pour next time, as it just adds to the residual gloop that builds up at the opening each time.
Ms. OP’s finger, no offense, is probably dirty, but the sugar and/or vinegar in the sauce, plus the dehumidification from the fridge should take care of that also.
Consider how long people leave condiments in the fridge under all sorts of circumstances and we’re not living in fear of old ketchup and mustard. If it’s an issue, a compromise of wiping it with a little piece of paper towel should resolve it for you guys.
