Largely cubed veggies into cooking blender e.g. thermomix = tmx

OR without tmx: smaller cubed veggies into pot with boiling water (amount as required in recipe, here 4c)

Add 4cups of hot water to tmx (if water room-temp, add 5min more to cooking time in next step)

Without tmx: boil veggies until buttery soft, ca. 20min

Bring slightly salted water to a boil.

When veggies done, turn temperature off and leave in pot / tmx with lid on

Without the cooking blender you could now place veggies into a normal thermoresistant blender OR

Use whatever you usually use to blend food in. This will take much longer of course manually, but don't give up. You might want to have blended your cashews first apart from the veggie mix and strain the last bits out before adding to veggies.

Add seasonings, optional turmeric, and cashews to pot or tmx with veggies

For tmx program 100°C 90sec speed 6 OR if using non-cooking blender, blend w/out the temperature option

The cashews probably won't be fully integrated and smooth, so continue blending for 60sec at highest speed

Pour ¾ blended veggie mix (should resemble melted cheese) over pasta and mix well

For 10min into 220°C oven

Let bake and check for melted cheese. Turn down to 170C as soon as melted and leave in 5min longer

Take out of oven, let stand 5min. Then portion and serve w/paprika mild or spicy - as you prefer

Depending on individual taste, you or your guests might want to add some salt and pepper over mac'n'cheese
