I don't know of any homemade recipe that you're specifically referring to. However, if you search the WEB for Wallpaper Retailers in England, maybe if you e-mail them, you'll get your recipe.
BUT, in case you're really just asking for a home made recipe for wallpaper paste, there are a few variations of it. Visit My Favorite WEB Search Engine and start perusing the links. (Some take a little time to load up so do be patient.)
I did search for varying combinations of wallpaper tub paste to no avail. The only downside I've heard/read about using this type of homemade recipe is that there's a potential for mold to grow. Remember, you ingredients are, well, food ingredients. And you know how food can 'spoil' over time. This end result may ruin your wallpaper. I don't know how to neutralize the mold problem. Perhaps someone else will.
