Can someone tell me where to buy this fabric?
When melted cheese is put in the fridge- it hardens, even if you reheat it, the texture has changed- and the fat has leaked outPasta when dried- after cooking it, will not re-soften, or rather, it doesn't resoften when bound to this cheeseIn a box you have fake cheese( dried powder) and dried pasta- there is NO moisture in the productPasta has flour and water in it- without the water it becomes little more than plasticSO, to keep macaroni cheese moist, you would need to keep it submerged in either water or milk- milk wouldn't be too badBut also don't expect your cheap macaroni cheese in powdered and dry form to hold any waterit's the cheapest most nasty version you can useThe pasta in real maracaroni should be thick, moist, spongey and you can press it together and it's doughy- the stuff in boxes you can't even crask with your teethThere is no moisture in it all allIf you made the same dish using fresh bendy pasta- you'd have soft and creamy pasta even after you leave it in the fridge overnightMake sure there is LOTS of sauce, that you add more than enough water to, to make sure the pasta stays moist.
If you are reheating it in the oven, then you could put some pet milk/evaporated milk in the pan so when it bubbled up it will make it moist and the cheese a little more creamy.
I agree with the first answer, that you should add a bit of milk, or just a couple drops of plain waterYou don't have to add the liquid until you're ready to re-heat it.
Nope, may not be organicLooks like a (possibly cotton) rib knit with a marled yarn (the specks)Hunting for the exact fabric used by a manufacturer is often an exercise in futilityBut look for rib knit or ribbed knit using a search engine like clusty.
