Platable

I have never seen or used the word.

I have never seen the word either. However, I would think of it as a visual word, 'capable of being put on a plate', meaning that the item came out well enough to look nice, rather than a mess (burnt, etc.).

Do you mean palatable? http://dictionary.cambridge.org/dictionary/british/palatable_1

Ahh yes thank you

Ok, as regards palatable, I've only run across it as meaning barely edible, something you'd only eat because you were hungry, or had no choice. "Eatable" in the sense that you could go on and eat more after trying that food.

"Mrs. Smith's stew was really bland, but I shook in enough salt and pepper to make it palatable."

Maybe it is a UK USA difference.

Did you enjoy the meal?
Yes it was very palatable thank you.

Meaning very tasty. This certainly agrees with the definition in the Cambridge dictionary (see link above).

From dictionary.com: delicious, delectable. Palatable, appetizing, tasty, savory all refer to tastes
