This hot pot has a harsh taste.
Literal
This hot-pot-dish [topic-は] acrid [emph-よ].
えぐい in its original sense means 'acrid / harsh / astringent' when describing food — the mouth-puckering bitterness of underripe persimmons or poorly prepared taro. In modern slang it's shifted to mean 'intense / brutal / gross,' but the food context (鍋物) anchors it in the original taste sense here.
