I used to toast these on the bars of the gas fire when I was a child. We used a fork hooked on by it’s prongs to the horizontal bars in front of the white ceramic blocks that the flames came up through.

Toasting the bottom of the crumpet first, then the top. It would get really hot and the butter would melt all the way down into the bubbled tubes of the crumpet. Delicious x
