You can get it from rockler.com or woodcraft.
This is only the second project I've used it on but really love the silky finish. For the bread box, I put on 3 thin coats. The Varnish Oil is like honey in the can so I thinned it down some using the Danish Oil (2:1). It is important that the shop be around 70 degrees when the piece dries or, like I did, I brought it in the house to dry for 24 hrs. between coats.
When you apply a coat, let it sit for an hour and then, using a soft cloth, wipe off any excess finish. After the first coat, I used #0000 steel wool on the bread box but applied the second and third coats directly after drying.
T&T Varnish Oil is the preferred finish for Christian Becksvoort - a well-known shaker-style furniture maker.

One other thing I like about applying the finish is that it is solvent-free and you can literally apply it without worrying about wearing gloves. And, it is food-safe.
