Maker Spotlight: The Former Pastry Chef Who Ditched the Oven for a Stone Grinder
Author: Cocoa Craft
At 4:17 every morning, Eli Navarro used to begin his shift by turning on six ovens.
By 4:25, someone was asking where the pistachios were. By 4:40, a mixer had jammed. By 5:10, the croissants were either perfect or personally insulting. And by 11:00, Eli had already answered the same question seventeen times:
“Can we get this dessert out faster?”
He loved pastry. He loved the precision, the heat, the drama of a soufflé behaving itself at the last possible second. But after twelve years in restaurant kitchens, he began to wonder whether his career had become less about making good food and more about sprinting between emergencies.
Then, during a particularly long service, Eli saw a video of a stone grinder turning roasted cacao nibs into chocolate.
The machine was not glamorous. It did not hiss, flash, or demand immediate attention. It simply turned and turned, granite wheels rolling through cacao, sugar, and cocoa butter until the mixture became smooth.
Eli watched for nearly ten minutes.
“Finally,” he said, “a piece of kitchen equipment with the correct attitude.”
Six months later, he left restaurant pastry behind and started a small bean-to-bar chocolate operation in a converted garage. His first major purchase was a countertop stone grinder, also called a melanger.
The oven was out. The grinder was in.
The problem with knowing how to make everything
Eli’s pastry background gave him a strong foundation. He understood ratios, temperature control, texture, emulsification, and the small details that separate “pleasant” from “I need another bite.”
But chocolate making introduced a different kind of patience.
In pastry, you often see the result quickly. A cake rises. A caramel darkens. A laminated dough reveals whether you folded it correctly.
Chocolate is less theatrical. A melanger can run for a day or two while appearing to do almost nothing. The changes happen gradually: coarse nibs become liquor, the liquor becomes smoother, acidity softens, and the flavor begins to settle into itself.
Eli found this both frustrating and liberating.
“I was used to adjusting a recipe every thirty seconds,” he says. “With chocolate, the recipe may need twelve hours before it tells you what it thinks.”
That became his first genuine teaching moment: a chocolate recipe is not just a list of ingredients. It is a sequence of decisions.
The cacao origin, roast, particle size, sugar choice, milk powder, cocoa butter, conching time, and tempering method all influence the final bar. Changing one variable can affect several others.
A successful batch is not necessarily the one with the fanciest ingredients. It is the one where the maker can explain what happened.
Eli’s first dark milk chocolate recipe
Eli started with a dark milk chocolate recipe because it connected his pastry instincts with his new bean-to-bar process.
He wanted a bar with enough cacao character to taste like chocolate: not sugar and dairy wearing a brown coat: but with enough milk powder to make the texture round and familiar.
His starting formula was simple:
- Cacao nibs for the main chocolate character
- Cocoa butter for flow and texture
- Fine sugar for sweetness
- Whole milk powder for creaminess
The exact percentages changed over several test batches. His early versions were too thick, then too sweet, then smooth but oddly flat. One batch tasted excellent but refused to temper cleanly. Another had a beautiful snap but a finish that reminded him of over-steeped tea.
That is the less glamorous side of artisan chocolate: the part where the maker writes “not quite” in a notebook and cleans chocolate from the underside of a shelf.
Eli learned to make changes one at a time. He adjusted the roast before adjusting the sugar. He tracked refining time instead of assuming longer was always better. He recorded whether the melanger was warm enough at loading and whether the milk powder had been added gradually.
He also learned not to trust memory.
“Memory is useful for remembering birthdays,” he says. “It is not a reliable batch record.”
For small craft chocolate makers, that distinction matters. A notebook can work for a while, but once you are testing several origins, batch sizes, and recipes, it becomes difficult to connect a result to the process that created it.
This is where digital tools can make the work calmer and more repeatable.
The gap between a good recipe and a repeatable product
Eli’s chocolate improved quickly once he began tracking more than the ingredient list.
He noted:
- Cacao percentage and batch size
- Roast temperature and duration
- Refining and conching time
- Ingredient lots
- Tempering observations
- Final texture and flavor notes
- What he would change next time
The information was there. The challenge was keeping it organized.
That gap: between knowing what you did and being able to use that knowledge later: is where many small operations lose time. A maker may have a brilliant formulation buried in a notebook, a phone photo, and three different spreadsheets. A production decision then becomes an archaeological dig.
Cocoa Craft’s Formulation Tool is designed to give that work a more practical home. It helps makers think through recipe structure, record experiments, and build a clearer history of what changed from batch to batch.
You can also create a free account on Cocoa Craft to start exploring the tools and build a workspace around your chocolate experiments.
No dramatic kitchen renovation required. No ceremonial throwing away of your notebook. You can keep the notebook. Eli does.
He just stopped asking it to do the work of software.
What the stone grinder taught him about production
Eli’s melanger became the center of his workshop, but not because it solved everything.
A stone grinder is excellent at refining and conching small batches. It can help turn roasted cacao nibs, sugar, and cocoa butter into a smooth chocolate mass over an extended run. But it still requires judgment.
The maker needs to load ingredients gradually, manage temperature, monitor viscosity, taste at sensible intervals, and keep the equipment clean. The grinder provides steady mechanical work. It does not decide whether the chocolate needs more time, less sugar, or a different roast.
That division of labor suits Eli perfectly.
He uses the machine for consistency and his palate for direction. The melanger handles the long, repetitive part. Eli handles the decisions that require experience.
If you are researching chocolate making equipment, look beyond capacity alone. Consider how the machine fits your batch size, workspace, cleaning routine, and production schedule. A stone grinder should be part of a system that includes roasting, cracking and winnowing, tempering, molding, storage, and recordkeeping.
The equipment is important. The workflow around it is what makes the operation work.
From restaurant speed to maker patience
Eli still misses parts of restaurant life.
He misses the energy of service. He misses the strange satisfaction of producing sixty identical desserts while someone counts down the seconds. He even misses the occasional pastry emergency, although he describes this as “the kind of nostalgia that should be handled carefully.”
What he does not miss is making decisions with no time to learn from them.
His new workshop runs more slowly, but it gives him better feedback. When a bar works, he can identify why. When it fails, he can usually find the clue in the process.
That is the real shift from pastry chef to craft chocolate maker. It is not simply trading an oven for a melanger. It is moving from fast execution toward controlled iteration.
The best small chocolate operations are built around that loop:
- Formulate a recipe.
- Make a batch.
- Record what happened.
- Taste and evaluate.
- Change one or two variables.
- Run it again.
That loop is the foundation of better bean-to-bar chocolate, whether you are producing weekend bars at home or building a professional production schedule.
It is also why Cocoa Craft exists: to help makers connect recipes, process decisions, equipment, and results in one place. Built by chocolate makers, for chocolate makers, Cocoa Craft is working toward the operating system for chocolate production: from the first experiment to the repeatable batch.
Join the Cocoa Craft Beta Test
Eli joined the Cocoa Craft Beta Test after losing track of which version of his dark milk chocolate recipe had the “good finish” and which one had the “surprisingly aggressive dairy note.”
The beta gave him a place to organize his formulations, test the workflow, and share practical feedback from an active chocolate workshop.
You can get free, unlimited access to the full Cocoa Craft software suite in exchange for monthly feedback. Join the beta at cocoa-craft.com!

And when your melanger is running and you need a short break from thinking about particle size, visit the Cocoa Craft Arcade. Play a quick game, earn points, and return to the workshop with your dignity mostly intact.
Eli’s former pastry colleagues still ask whether he misses the ovens.
His answer depends on the day.
“I miss the ovens,” he says. “I do not miss six of them.”
Then he checks the grinder, tastes a sample, and writes one more note in the batch record.
“Better than yesterday,” he says. “Run it again.”
