Which finish for wooden salad bowl

[cally60]

I am planning to turn a salad bowl. Most likely English Walnut, but might be Spalted Beech, as I have a suitable stock of both.
I’m wondering what finish to use, that will be OK with a vinaigrette dressing, which is obviously naturally acidic.
Any ideas recommendations or previous experience of this?

I did a bit more research, and can now answer my own question.
After speaking to the technical support person at Chestnut Products, I am confident that their food safe oil will be ok for this.
