The only stranded - solid connection that I trust is solder. You'll
likely get about 37 other different opinions...
I thought a connection that relied on solder was a code violation?
Yeah. I think it's in the wiring methods article. Don't remember the
exact section off the top of my head.
You can 'tin' the stranded end so it acts more like solid wire under the
wire nut.
Tin it with solder? Will it hold together when I twist it?

The only places the US NEC forbids the use of solder is in connecting
grounding or bonding conductors to electrodes and connecting Equipment
Grounding Conductors to boxes. In both cases the connection may not be
"depending on solder."
250.70 Methods of Grounding and Bonding Conductor Connection to Electrodes.
250.148 Continuity and Attachment of Equipment Grounding Conductors to
Boxes.
In other applications the US NEC specifically permits soldering vis.
[110.14 Electrical Connections.
Because of different characteristics of dissimilar metals, devices such
as pressure terminal or pressure splicing connectors and soldering lugs
shall be identified for the material of the conductor and shall be
properly installed and used. Conductors of dissimilar metals shall not
be intermixed in a terminal or splicing connector where physical contact
occurs between dissimilar conductors (such as copper and aluminum,
copper and copper-clad aluminum, or aluminum and copper-clad aluminum),
unless the device is identified for the purpose and conditions of use.
Materials such as solder, fluxes, inhibitors, and compounds, where
employed, shall be suitable for the use and shall be of a type that will
not adversely affect the conductors, installation, or equipment.
(B) Splices. Conductors shall be spliced or joined with splicing devices
identified for the use or by brazing, welding, or soldering with a
fusible metal or alloy. Soldered splices shall first be spliced or
joined so as to be mechanically and electrically secure without solder
and then be soldered. All splices and joints and the free ends of
conductors shall be covered with an insulation equivalent to that of the
conductors or with an insulating device identified for the purpose.]
