Joan,
( I think it's just you...

)
I had a similar issue with finding High Gluten flour for making bagels from a King Arthur recipe ( my posting is at:
viewtopic.php?f=4&t=5294&p=52918&hilit=bagel+deb#p52918). I ended up adding vital wheat gluten to KA bread flour in the proportion listed on the VWG package- I think it's 1 t per cup of flour. ( If your package doesn't have a proportion, let me know and I'll go look mine up). I found it worked very well- but I hadn't tried the recipe with the Sir Lancelot to be able t determine a difference.
If your recipe calls for Barley malt, I'd be happy to give you some - I've got far more than I'll use in a very long time....
