Clue: Riot brewing about unlimited people cooking chicken in Indian style (8)
Answer: TANDOORI
Explanation: Definition: cooking chicken in Indian style
ANDO in RIOT, and I think the ANDO must be "unlimited" [M]ANDO[M], unless anyone has a better idea. *A much better idea from Muffyword and NeilW – the "people cooking chicken" are the restaurant chain NANDO'S, making the definition the more satisfactory 'Indian style'
