Can I as a Bloodhunter create mutagens without doing a short or long rest?

As a 2020 version of the Bloodhunter/mutagen order, at lvl 3 I can create one mutagens in a short/long rest.

I read this handbook:

As a possible fix: Instead of preparing your mutagens during a rest, you prepare reagents for mutagens.

Creating a mutagen requires one minute of uninterrupted work with these reagents and a set of alchemist’s tools. This allows the Blood Hunter a bit more flexibility with their mutagens, but not so much that they can change them during combat."

I don´t really understand where he gets that with the reagents. I can´t find it in the books and nothing about it on the internet.

This way I could do a 1 min pause and prepare the mutagen without doing a short rest.

I hope you can help me to understand it better.

Can a Bloodhunter Mutant consume Mutagens towards the end of a short rest?

I’m considering playing a Bloodhunter Order of the Mutant (Updated Version). Starting at 7th Level one gains the Reconstruction Mutagen:


Prerequisite: 7th level For 1 hour, at the start of each of your turns, you regain hit points equal to your proficiency bonus if you have at least 1 hit point, but no more than half of your hit points.

The Text of Mutagencraft reads as follows:

As a bonus action you can consume a single mutagen, and the effects and side effects last until you finish a short or long rest, unless otherwise specified.

Due to the 1 hour Duration of Reconstruction the effect would outlast the end of the short rest effectively pushing the number of active mutagens to 3.

Much later at Level 18 this becomes much more interesting due to Exalted Mutation

As a bonus action, you can choose one mutagen currently affecting you to flush from your system and end, then immediately have a mutagen you know the formula for take effect in its place.

Enableing you to switch the 1-hour duration mutagen to a long term one, at this point effectively enabling you to be under the effect of up to 5 long term mutagens at a time.

The Text of a short rest specifies the activities one might take during that rest:

A Short Rest is a period of downtime, at least 1 hour long, during which a character does nothing more strenuous than eating, drinking, reading, and tending to wounds.

Consuming a mutagen in my mind would count as drinking or eating something.

Am I missing something here? Is this possible? Would you allow for this in a game?
