I find this method the best and been working fine.

First, put the feed in a little plastic zipbag

Second, thaw them in the cold water first
(Instantly thawing frozen/very cold item will thaw unevenly or just imagine cooking frozen stuff that you eat without thawing them but throwing them right on to the hot pan)

Third, after the feed is all thawed, change water to warm/ -ish hot water.
(It should be mild warm or so)

Finally, take the feed out of the bag and hairdry it for about 2 minutes.
