Cheers. I haven't experimented (nor thought of) that point - but I will when I get the chance. I don't think it would be a problem - the liquid would only follow the spiral when the spoon is almost upside down. In fact it may help stop liquid running down the handle - not that I ever hold my spoons so that liquid runs down them! The channel starts from the back not the front.
Apple really is a nice wood. It's not too hard to work when seasoned and has a lovely grain. But burning it is good too!
