You say walnuts; I say pecans. :-)
I’ll grant you pecans. But not chopped more than in half.
After reading this thread I had to go make hot cocoa. Oven was engaged so could go crazy and make what I always have called chocolate pudding cake. :-)
I use pecans in many recipes that call for walnuts. The pecans are sweeter and ‘crispier’.
I like to just eat walnuts out of the shell; reminds me of when we got them in our Christmas stockings - the only time we ever had them in my chldhood - and had to take the nutcracker to them ;-)
