One of our favorites, made this a dozen times. Lovely with some sugarsnaps on the side. Do use a decent quality harissa, eg Tesco one is not really good.

Delicious! Not the easiest of recipes, and needs some tweaking (less juice and zest, more oven time) but still went down really well.

I found the mash far too sweet and the fish seemed to be overpowered by everything else

This was also by far the worst recipe I've tried from GF! Just wish I'd read the reviews beforehand like I usually do... Too mushy, no textures, like mentioned before the lemon was too much and so was the ginger and the fish was under cooked! Needs work!

this is so simple and so tasty, made more of the harrisa butter and used that to mix in with the mash along side the ginger

Absolutely delicious! I only used half a lemon and omitted the garlic but loved the sweet potato with ginger. Easy to make dairy free - I used a DF spread instead of butter with no problems, and a splash of olive oil in the potato to mash it. Used a heaped tsp of harissa to give it a real kick. Will be making again!
