Question about a Mutant Zucchini

[The empressof all]

I found a huge (half an arm sized) zucchini hiding in plain sight in the garden. Great...I have everything in the pantry for zucchini bread so thought I'd spend a few hours in the kitchen. I went to slice it open to start shredding it and it was hard like a winter squash. When I did get it cut the flesh was yellow like a butternut. What happened? Do zukes go hard when they reach a certain size. (Oh jeeze.....Keep it clean folks....we're talking veggies)

1. Learn something new every day...

Apparently when they're fully mature the skin will harden.

2. Our squashes miscegenated

so at least in our yard, if you discover a new species, it's probably inedible. :shrug:

4. Well I wound up cooking it

After I managed to get it into two pieces, I roasted the two huge parts until softish. I let cool and scooped out all the seeds. The cooked flesh was yellow but with a texture more like zucchini than butternut. It was very very wet so I stuck it in a colander to let it drain a bit. We ate some last night with dinner and woke up this morning so it didn't kill us. I'm going to mix the rest with some parm and bake it with a breadcrumb topping. I'm gonna hack up the other one and bake that one off too today.
