Hey, just a tip for those wanting to try an alternative, you can soften the spaghetti above in the varoma whilst making sauce below, it softens quite a bit, then you can add to the jug and finish it off. I have done this when making a pasta dish with clams in tomato sauce, it worked really well.
I did the tuna with spaghetti on Saturday at a delivery demo; we used spaghetti and didn't break it - it came out beautifully I was very impressed needed a few minutes longer to cook as it took time to go soft and sink into the sauce. We also use 2 tins of tuna and less pasta than the EDC.
