Temporal ambiguity on mochiko packaging


I am making some shiratama mochi and want to know if I have to scoop the mochi
out after they rise, or 1-2 minutes after they rise:

> だんごが **浮｛う｝きあがって１～２分してから** 順｛じゅん｝にすくいあげ、冷水｛れいすい｝にとって、さまします。

My first thought was that I am meant to wait until 1-2 minutes after the dango
has risen before scooping it into cold water, but the presence of ～てから makes
me suspect that the １～２分 is actually an approximation of how long it will take
for the dango to rise.

Also, optional bonus question since the は and が differences always challenge
me:

Why is が being used instead of は, and would using は instead change anything?




When a series of actions is listed with the verbs in the ～て conjunctive form,
the list can parse out to "`[VERB]`, then `[VERB]`, then `[VERB]`..."

Years ago, a friend of mine at work laughed after getting off the phone with
his wife, when he realized that she'd explained her day using almost entirely
～て-form verbs. My memory is fuzzy, but it was something like,

> 連れて行って話して、帰って食べて寝た。

_"With [someone], we went, and talked, then [I? we?] returned home and ate and
had a nap."_

Here's your sample sentence:

> だんごが **浮｛う｝きあがって１～２分してから** 順｛じゅん｝にすくいあげ、冷水｛れいすい｝にとって、さまします。

Let's break this up.

> だんごが浮｛う｝きあがっ **て**

The dango float up, _and then_...

> １～２分し **てから**

_after_ giving it another 1 to 2 minutes, _then_...

> 順｛じゅん｝にすくいあげ、冷水｛れいすい｝にとっ **て** 、

scooping them out in order (i.e. in the order in which they floated up), put
them in cold water, _and_...

> さまします。

cool them off.
