Gravy, mmm, this is what most low fodmapers miss the most. I have found a ready-made beef stock from Atkins & PottsĀ https://www.atkinsandpotts.co.uk/products/stocks-gravies/17-stocks-and-gravies/P2724-beef-stock it does contain lemon juice concentrate, but as the stock ingredients consist of only 5% of the end product, this is unlikely to prove problematic. Not all of their products are suitable for the low fodmap diet, but this beef stock is handy and not too expensive compared with other specific low fodmap products. Some of you may notice there are only five sausages in the picture – hubby couldn’t wait and ate one of then during the preparation!
Ingredients
Gravy
1 pack of Atkins and Potts beef stock
2 teaspoons of gluten-free flour

80g swede

Method
Prick and grill the sausages for 20-25 minutes until cooked
Peel, season and boil the potatoes in salted water for 20 minutes and mash
Mix the 2 teaspoons of gluten-free flour with water to make a paste and add this to the beef stock in a pan, keep stirring and cook until thickened to your preferred thickness, add hot water if it is too thick for your taste.
Peel and chop the vegetables and spray in oil. Add the peppercorns and herbs and roast in the oven – gas mark 6, 200 degrees C until soft.
Combine and enjoy before venturing out into the cold for bonfire night!

I am definitely going to have this saussage and mash tonight, if I can find a low FODMAP vegetarian saussage
