kušati

1. (+ acc.) to test; to tempt
   Nemoj da kušaš moje strpljenje! — Don't test my patience!
   Ne treba kušati sudbinu. — You shouldn't tempt fate.
2. Croat. (of food) to taste; to sample

In the sense 'to taste food or drink', kušati is more characteristic of Croatian usage but also occurs in Serbian, especially in literary language; in Serbia the usual word is probati, or degustirati for wine and similar products.
