Madam Modesta 14th May, 2017 I noticed a few reviews mentioning that this was bland. Therefore, I would strongly recommend using the tomato sauce recipe here: https://www.bbcgoodfood.com/recipes/339605/tomato-sauce as suggested so your sauce is slightly sweet. I changed a couple of things though... I doubled the recipe (although you can be fairly liberal with the sauce proportions) for the sauce and used a tablespoon of caster sugar, cooked the onion and garlic in wine BEFORE adding the veges and also replacing some of the water (to reduce) with wine. The one tablespoon of treacle is fine. I used eight sausages, a heaped teaspoon of the mustard and 2x400 of beans this time round. I served it on rice (my partner is Vietnamise). It was particularly delicious and lasts a few days.
