Which British curry is widely associated with Glasgow and consists of chicken in a spiced tomato-based sauce?

The British curry widely associated with Glasgow that consists of chicken in a spiced tomato-based sauce is chicken tikka masala.

The dish combines pieces of chicken tikka with a creamy, seasoned sauce commonly containing tomatoes, onions, garlic, ginger, and spices. Its exact origin is disputed, but it became strongly associated with British Indian restaurants during the late 20th century.

Glasgow is frequently linked with the dish through a story involving chef Ali Ahmed Aslam of the Shish Mahal restaurant. The story says the sauce was developed after a customer found chicken tikka too dry, although historians and food writers continue to debate the details.

Chicken tikka masala is often confused with chicken tikka. Chicken tikka is grilled or roasted marinated chicken; tikka masala adds the characteristic saucy preparation. Recipes vary substantially between restaurants.
