beetlbumjl, how about if you very gently and carefully swirl the pot while holding the lid on instead of taking the lid off? It does seem like stirring is the biggest issue (perhaps moreso with a small volume like this?), and it reminds me of boiling pasta - i.e. tradition said you need to stir a few times throughout to keep it from sticking together, but in reality if you just give it a decent stir right at the start it does fine. I wonder if the mash might work similarly (I notice in Deathbrewer's stickied BIAB posts he only stirs a couple times.) That is my completely uninformed, speculative opinion.
