This here, you need to be careful with food prep areas...there is a reason butcher blocks use only mineral oil....a worktop isn't a piece of furniture.I wouldn't be using any chemical laden products such as Danish oil unless they are specifically labelled as food safe.
Danish oil gives a bit of a gloss if that's your thing and to echo the above it does always feel tacky, I would recommend a mix of food safe mineral oil and organic beeswax, melt it all down in a pot and you can change the ratios to get a consistency you like for application.
Works great, looks great and is cheap.
I’ve always used Danish Oil. Blather it on, moving it about until there are no dry patches, wipe off the excess, let dry and repeat until it will take no more.
Edit; just looked at @eLuSiVeMiTe linky, and thats what I use.
