We went to West Wales, stopped in a cafe and sampled a Glamorgan toastie.
It was absolutely delicious.
I asked what was in it and was told …leeks, onion marmalade, mustard, and cheese.
Does anyone have a recipe for this?
Very funny, (in a happy way… not sarcastic way) but I guess you haven’t tasted one?Get some leeks, onion marmalade, mustard and cheese and whack it between two pieces of bread. Stick under grill![]()
Don’t knock it until you have tried itmarmalade in a toastie sounds as disgusting as pineapple on a pizza![]()

To be honest, I have never tried or heard of onion marmalade before having one of these toasties. The fact that it was so delicious has made me look further into how it was made.Orange marmalade, maybe. But onion marmalade is a different beast.

You won't be thanking him when you get the invoice for site visits and sample costsYes please. And thank you![]()

That’s brilliant, sounds exactly what I’m looking for.The way I make it/them
Fry off half a leek and half an onion, finely diced, in some butter, then add some finely shredded leftover sprouts or green cabbage till it's all nice and soft.
Butter slices of farmhouse bread one side, mustard the other side, then cover mustard side with cheese, add your filling of onions, leeks and cabbage, more cheese then the top layer of bread, mustard side down.
I have heard of people using marmalade, honey or apricot jam, mango chutney, onion marmalade, beetroot, picked onion and all sorts of things to give it a twang but I've never tried personally.
Once it's built, fry on a Low heat butter side down, press down with a spatula to ensure good contact, flip as needed. Cook 1 at a time to keep the heat in the pan until the cheese has melted and bread is golden.
You can also use some ground sausage meat to make it Interesting and I have in the past used bacon lardons occasionally.
Plenty of salt and pepper in the filling, you can substitute mustard for most any warm condiment, bit of washyoursister sauce can be nice as well.
As for cheese selection, any hard and melting cheese will do, I use mature cheddar and red Leicester most of the time but some chilli cheese makes a nice change every now and then.
This is one of those dishes that can be altered and modified in so many ways to suit your tastes that I can be made out of almost any ingredients in the same category as the ones above, but the method above came from my grandmother that was born and raised in Llanelli and she called it something different, but I came to learn it's essentially the same recipe
The details there are enough to make 1 toastie, obviously you can double up as needed for more. The ratio of ingredients isn't really relevant either so you could go heavy on the onion and lesson the leek to suit your tasteThat’s brilliant, sounds exactly what I’m looking for.
Thank you for taking your time to give so much detail![]()

Why not live dangerously and try one?Nope I grew up in N Wales where I can't imagine they would ever consider such a concoction. Sounds yummy enough though.
BTW my local farm shop does lime marmalade which is my favourite![]()
