I have found that italian 00 flour varies enormously in the amount of liquid it can absorb, so It can be a bit hit or miss. What do you roll it with? I use an attachment for my kenwood and the last lot I made, barely held itself together, but was perfect in texture when extruded. If you roll in a pasta machine make it as dry as possible as repeated rolling through makes it hotter and wetter and stickier! That said, I usually make all the pasta up and then freeze any I don't use immediately.
