Looks like you could have gone quite a bit hotter for the sear. I use Alton Browns method on a skillet. Leave it on high for 10 minutes. Should be hot enough to evaporate a teaspoon of water in seconds. Lightly oil the steaks with peanut oil. Then sear each side for 45 seconds. It will set off the smoke alarm, though, if your stove vent isn’t great.
Yeah that’s a good point. You’ll definitely want to dry off the outside before searing it if you go sous vide over oven. The few times we have used sous vide for chicken or steak, she complains that the texture is too weird. I don’t notice it though. But apparently that is a thing. Might have something to do with the moisture issue you are talking about.
