Show Notes
Ron Cardwell, Director of Commodity Strategy at Restaurant Technologies (RTI), runs point on cooking oil for the company that pioneered automated oil management — the closed-loop system that delivers fresh oil and pulls used oil out of more than 40,000 restaurants. We get into the seed oil debate, allergen myths, beef tallow's comeback, and what actually happens to the used oil in your fryer.
Ron's nickname is "The Oil Nerd." He earned it. He started in soybean processing out of college, fell in love with how oil touches every corner of food and energy, and has been deep in commodity strategy ever since. RTI moves more than 700 million pounds of fresh oil into restaurants every year and pulls hundreds of millions of pounds of used oil back out — and almost all of it ends up as renewable diesel, biodiesel, or sustainable aviation fuel.
We dig into how operators should actually think about oil — flavor, function, and price, in that order, not the other way around. Why "buy the cheapest" is a trap that costs you more in turnover and bad food. The seed oil vs. beef tallow debate — what's signal and what's noise, what the real trade-offs are on flavor, supply, and price when you switch. The allergen question that comes up at every front-of-house every week — and why a fully refined and deodorized oil doesn't carry the allergen at all (Ron settles this one on tape). What pourable beef tallow actually is and why it exists. Why high-oleic crop breeding is changing what "stable frying oil" even means. The full-circle history — beef tallow → saturated fat fear → trans fats → seed oil blends → consumers asking for tallow back. And the part of Ron's job he loves most: turning used fryer oil into renewable diesel at roughly 20% the carbon intensity of conventional diesel.

Born into a poor family in Peru as the youngest of five children, Daniel Valverde’s path to winemaking began far from the vineyard. At nineteen, without a college degree, he followed his older siblings to the United States and took a job busing tables on weekends in New Jersey while juggling shifts at a local supermarket. Grinding his way across restaurant floors, he eventually made the leap to New York City to work at the historic steakhouse The Palm, rising through the ranks from server to floor manager, beverage manager, and eventually sales manager. It was there that he met fellow server Max, sparking a late-night pact to one day make wine together in Peru. Driven by an entrepreneurial streak forged in the US, Daniel later stepped away from the corporate dining world, survived a battle with thyroid cancer, and relocated to Puerto Rico on an impulse in 2021. There, he founded Green Rose Cleaners—scaling it from a solo hustle into the island’s highest-rated commercial and residential cleaning service. That venture provided the operational freedom to return home to Peru and finally fulfill his promise: founding Valtierro to prove that Peru’s heritage grapes belong on the world’s finest dining tables.
First time in New Orleans, and I nearly choked on powdered sugar within the first hour. Worth it. Down for three days, so I did what I do and ate everything. I have opinions on the turtle soup (I grew up in the sticks, it's turtle soup, guys). I found a boudin egg roll that was one of my favorite thing I ate all trip. I walked Bourbon Street after everyone told me it'd be a disaster, and it wasn't. Best meal of the trip? Lufu which is Indian food. In New Orleans. Go figure. Go watch this one on YouTube, because me describing a plate of food with audio only gets old fast. Everything I mentioned is listed below. Tell me what I missed, because I'm going back, and next time it's crawfish season. Catch you on the sunny side.
