It's definitely suitable with barbecued stuff, though in summer I would be much more likely to buy corn on the cob. If hosting a formal dinner, where cobs are unthinkable, I buy frozen corn.   

I have never heard of anybody preparing creamed corn. We buy a can of it and heat it up. Butter optional. Actually, I haven't seen it in years.

I'm sure your own creamed corn was much better than ours. It sounds like a lot work, though.

As for consistency, it's between mushroom soup and mayonnaise.
