Don't use the carpet, it doesn't look very sanitary. Instead, use a hard white surface, and make sure that the wood you've placed it on looks dry 馃樁鈥嶐煂笍
I would personally use a slate slab or similar to put the food on since it needs to contrast with the bright color, but that's just my preference.
@MartinTheFirst If you want to use wood, then get a darker color that doesn't show if it's moist and also contrasts better, or alternatively add a finish to the wood that stops it from absorbing the moisture.
