Long time lurker first time baker….

I’m not really sure what’s gone wrong… 600g Flour, 11g Salt, 3g Sugar, 380ml water, 10g Yeast… my dough rose beautifully, I made it into 2 baguettes… put it in the oven and it’s come out really quite doughy… and heavy… Tastes OK, but I don’t think you’d make a sandwich with it
