Just some notes amplifying Tino27's comments.
"Steam". Yes use hot, or better boiling, water. NEVER ice.
Ice produces
visible fog - which the gullible think of as the "steam" that you want.
BUT if you can see it, it must be below the boiling point of water (212F/100C at sea level). You'd like the water vapour to be at oven temperature.
And at that temperature, its invisible. Because, at oven temperature it is in the form of
real vapour, rather than a mist of
tiny droplets of liquid water (which cannot exist above 212F/100C, sea level, standard air pressure).
So rejoice, don't worry, if you "can't see it" -- that doesn't automatically mean that it has left the building.
"Instant-mix yeast". Its great stuff.
But, if you can, avoid "bread machine" yeasts loaded with 'improvers'. (Check the ingredients listing carefully - ascorbic/ascorbate/VitaminC is benign, and stearate is what makes it mix instantly - anything else is unfortunate.)
And be sure to use LESS of it than you might with "active dried". About 1/4 less. (Regardless of what the
US yeast manufacturers say.)
For storage, there's no need whatsoever to keep instant mix yeast in the freezer. Its storage enemy is dampness. Freezing and defrosting tends to produce condensation. Which is bad.
So store it cool (that's to say not hot), but more importantly, SEALED and DRY. You can keep your working supply (maybe a month's worth) in a small sealed jar (or snap-lock box) in the fridge, with your stockpile in a different jar (so it only gets opened occasionally). A FoodSaver (or similar VacPac) bag is ideal for the stockpile, but not so practical for your 'using' supply.
"Time".
Fermentation time is an essential ingredient of good bread.
But like any other ingredient, an excess is counter-productive. Bread dough goes flabby and flat with excess fermentation.
Fermentation time and temperature are related (in a very non-linear way).
But yes, longer (and cooler) gives more flavour.
And if you use a bit less yeast, fermentation will take longer at a particular temperature, resulting in even more flavour - and incidentally, bread that goes stale more slowly!
And that takes you towards biga, poolish and sponge methods.
To see where this thinking ultimately leads, read (but don't necessarily live by) Reinhart's Whole Grain book.
Enjoy!
