This was really good, I particularly love the use of apple, it gives the curry a delicate sweetness without overpowering. I didn't have cooked chicken, so sauteed a couple of diced chicken breasts. I used a Roasted Garam Masala for the curry powder, and I cooked the curry for a bit longer than directed, I felt that the sauce had a good consistency and so didn't add the cornflour. This was a really good, mild, curry that I think would appeal even to non-curry lovers. I wouldn't recommend spicing this one up, as you will lose that lovely sweetness from the apple. I enjoyed the use of celery and mushrooms too, overall, 10 stars, lovely dish, thank you Jackie! Made for PRMR tag game.
