Hi JimJam, I would count the Tesco pitta bread as HEB + 1 syn as the Asda one is 6.5 syns and your Tesco one is 7.5 syns. I looked on the Tesco and Asda websites and did a comparison between the two pittas and they're very similar;
ASDA Per pitta
Kcal: 132
Protein: 7g
Carbohydrate: 24g
Sugars: 0.9g
Fat: 0.9g
Saturates: 0.2g
Fibre: 3.3g
Sodium: 0.11g
TESCO Per pitta
Kcal: 145
Protein: 6.7g
Carbohydrate: 26.2g
Sugars: 2.0g
Fat: 1.5g
Saturates: 0.2g
Fibre: 5.2g
Sodium: 0.2g
The Tesco one is a little higher in calories, salt, carbs, fat and sugar. They have the same level of saturated fat and the Tesco one is much higher in fibre than Asda. So obviously because the Tesco one is higher in calories, that accounts for the 1 syn extra. Its 13 Kcals higher than the Asda one and according to SW 1 syn = roughly 20 Kcals.
I don't think each type of pitta bread has to be made in exactly the same way with identical ingredients to be considered a HEX. Besides, how many ways are there to make pitta breads anyway? LOL! Just like regular sliced bread, I imagine that most pitta breads are made basically the same and if there are any differences in fat, calories, sugars etc, then the difference would be reflected in the extra syns.
I personally LOVE the food doctor multi seed & cereal pitta bread which has less sugar and double the fibre when compared to the Asda one. Its got more fat from the seeds in it and therefore more syns but from the nutritional value I'm more inclined to buying this and synning the difference than the Asda one.
The whole pitta bread issue seems to be a contentious subject so at the end of the day everyone should do what they feel comfortable doing. I don't see it as bending the rules if you eat a similar alternative to SW endorsed healthy extras and counting any added syns there might be. But that might just be me cuz I'm a gemini and I question everything
