This. If you want to hold on ice, you must be able to stack all of your weight such that you can come down hard on the side edge of the ski in the part of the arc where the turn forces are trying to pop the ski loose. As Brooks Dodge once famously said, "the best way to stop a skid is not to start one". So you must start with a clean transition without any kind of steering. Once on your new edges, you must balance through the top third of the arc. Spend that time getting yourself ready to increase the tipping during the middle third of the arc. You can't ever let your skis get out from under you. In the bottom third of the arc, you had better be in position to come down on the side edges to keep the ski gripping.
But really, this all comes down to developing the Essentials. You must tip cleanly to new edges. You must never push off or extend (or you will imediately break the ski loose). Flex to release and allow your stance leg to get long as you move into the turn, while still staying over your skis--which means counterbalancing is critical. To really and truly hold, you must be able to get your feet well behind your hips and you must also have strong counteracting.
As a starting point, I would suggest trying to ski slow, brushed turns on gentle terrain with the Super Phantom transition with focus on transfering weight completely to the new stance foot as part of your release. Brush the turn, but end up standing on that outside ski with everything you have. As Co_Steve mentioned, you must have ankle and leg tension in the stance leg. If you aren't carrying tension in the ankle, the edge angle will decrease and you will lose grip.
As you progress to blue terrain (and beyond) you will need to counteract *and* counterbalance in order to hold. When you counteract, it causes your counterbalancing movements to be directed out over the ski; i.e. you will feel like you are leaning out over the fallline. If you don't do this, if you don't get over your skis, they will slide out from under you. You can help that movement by paying attention to the inside hand--it needs to end up nearly over the LTE of the inside ski at turn finish.
There isn't any magic to skiing ice, but you do need all of the Essentials. If you are struggling, keep working. Raise your game enough and skiing ice will just start working for you.
