I've struggled to get consistently tender chicken for a while. I like tikka style and have tried some of the preferred tikka recipes on here, but always found them a bit dry or tough.
But recently I have found a recipe/method that works perfectly for me every time - and I thought I'd share it - just in case anyone else was struggling.
It is tikka/tandoori style chicken, intended for use in a curry.
Ingredients3 or 4 chicken breasts
Lemon juice
Salt
Tandoori masala
Method1/ Trim chicken and cut into pieces which are about twice the size you want in final curry and pierce the skin side of the chicken several times with a sharp knife. Place in a bowl or on a tray, skin side up.

2/ Sprinkle some salt over the chicken (about 1 tbsp) and rub into the chicken (take a minute to coat them)
3/ Sprinkle a few glugs of lemon juice over the chicken and rub this in well.
4/ Turn over chicken pieces and do the same on the other side.
5/ Set aside for about 30 minutes. The lemon and salt should have started to make inroad into the chicken and turn the edges white.
6/ Sprinkle Tandoori masala (I'm using Rajah at the moment) over chicken and mix well, using a blunt spoon. Use the back of the spoon to rub the powder into the chicken.

7/ Cover with cling film and refrigerate for 24 hours or overnight. Stir and rub in spices two or three times if possible.
8/ When ready to cook, pre-heat oven to 180 C (fan assisted)
9/ Place chicken pieces on a baking tray and cook on middle shelf for ten minutes. After that, the top should be dryish and the bottom still moist.

10/ Turn each piece over and cook for another 10 minutes - meanwhile melt some butter.
11/ Turn oven up to about 210-220 (probably more if you want burnt bits) remove chicken and turn each piece over again. Brush top side with melted butter and return to oven for 4 - 5 minutes. Keep an eye on it in case it burns.
12/ Remove from oven, turn each chicken piece, brush with melted butter and return to oven for another 4-5 minutes - again watch it.
It should come out kind of like this

13/ Take the thickest piece and cut through the middle to ensure it is cooked through

And there you have it - beautiful, tender chicken every time

Cut pieces in half, add to desired curry and enjoy. If you wish to reheat, I put in oven at about 150 C (covered) for 10 or 15 minutes before adding to curry.
Most people probably have their own methods, but this might help someone
