Oh, soggy fries! I know teh feeling! It's utterly disheartening, isn't it??? My family loves a good fry with our BBQ, especially when we're grilling up some burgers or sausages... my husband always says my fries are teh best when I get them right, but it's such a faff sometimes, LOL.
The absolute clutch move, as you call it, is definitely the double fry!!! You have to fry them once at a lower temperature, just to cook them through and make them soft... then you take them out, let them drain a bit, and really crank up teh heat for the second fry. That's where they get all golden and wonderfully crispy! Also, rinsing them really well beforehand to get rid of all that starch... and drying them completely! I mean, completely dry!!! That's another really important bit, IMO. I once tried a wierd trick with baking soda in the water, but it just made them taste odd, so stick to teh basics, eh? Hope this helps your binge-watching sessions!!! :)
