The added ‘Yum’ meaning ‘to mix hot and tangy ingredients’. Combine the grilled pork neck with a sweet, sour, salty and hot salad and perfection. The signature combination of Thai tastes is the reason why Yum Kor Moo Yang sits top of my Top 10 Isan Food list. Yum Kor Moo Yang is best found in evenings at Isan roadside barbecues along with me and some beers.
