My hand is hovering near the radio dial, frozen in the mid-air arc of a reflex I thought I had buried 17 months ago. It is the first week of December, and the air in the kitchen has that specific, brittle cold that smells of coming snow and old wood-burning stoves. Without thinking-without a single conscious permission slip from my frontal lobe-my throat begins to tighten with the first three notes of a carol I haven’t sung in years. It’s a phantom limb. I am a Jewish woman now. I have the papers, the Hebrew name, the 7-branched candelabra on the mantle, and a library of texts I have studied until my eyes blurred into a soft focus. My brain knows exactly who I am. My brain is convinced. But my body, it seems, is a slow learner, a stubborn animal that still expects the bells to ring when the frost hits the glass.

It is an exhausting way to live, this dual-occupancy of the self. I spent the morning arguing with a colleague about the structural integrity of a new honeycomb brittle-I am an ice cream flavor developer by trade, a job that requires an obsessive devotion to the chemistry of memory-and even though I was objectively right about the crystallization point of the sugar, I lost the argument. I lost it because the other person was louder, more established, and frankly, more comfortable in their skin. Being right is a cold comfort when your own physiology feels like an uninvited guest in your life. It left me with a bitter taste, sharper than the 97 percent dark chocolate I keep in the lab for testing.

Teaching the Tongue to Forget

Ella M.-C., a woman I work with who can identify the provenance of a vanilla bean with a single sniff, once told me that the tongue never forgets a trauma. If you burn your mouth on a batch of scalding caramel when you’re seven years old, your tongue will recoil from that specific scent for the next 77 years. I think conversion is a bit like that, but in reverse. You are trying to teach the tongue to love something it didn’t grow up with, and to forget the warmth of the thing that once fed it.

We treat religious transition as if it’s a series of checkboxes-read these 37 books, attend these 17 classes, answer these questions before a panel of three men. But no one tells you about the muscle memory of your own knees, which still want to bend at the wrong moments, or the way your heart rate spikes when you hear a certain hymn drifting out of a storefront in late autumn.

In the lab, I spend my days trying to replicate emotions through fat and sugar. If I want to evoke ‘nostalgia,’ I don’t just throw in some cinnamon; I have to calculate the exact mouthfeel. If the fat content is even 7 percent too high, the flavor coats the tongue and prevents the memory from triggering. It’s precision work. And yet, here I am, unable to calibrate my own internal setting.

The Collision of Rituals

I love the intellectual rigor of the Talmud; I find the cycle of the moon far more grounding than the arbitrary Gregorian calendar. I am at home in the synagogue in a way I never was in the cathedral of my youth. And yet, when the seasons shift, my skin feels tight. It feels like I’m wearing a sweater that was washed too hot-not quite fitting, slightly itchy at the neck.

This is the contrarian reality of transformation: the mind moves at the speed of light, but the body moves at the speed of erosion. You can change your philosophy in a single, shattering afternoon of realization, but you cannot change the 207 bones in your body that have been conditioned by decades of specific movements. When I was a child, my mother used to take me to the 7:00 PM service on Christmas Eve. The smell of damp wool coats and beeswax is hard-coded into my limbic system. Now, when I smell beeswax, my brain says ‘Havdalah,’ but my subconscious says ‘Silent Night.’ It’s a sensory collision that leaves me feeling dizzy, like I’ve stepped off a curb that was 7 inches deeper than I expected.

The Flavor of Dissonance

I think about Ella M.-C. again. She spent 27 months trying to perfect a ‘burnt toast’ ice cream. The problem wasn’t the flavor; it was the psychological dissonance. People loved the taste, but their brains couldn’t reconcile the cold, creamy texture with the dry, charred expectation of toast. They would gag even as they admitted it tasted good.

That’s where I am. I am ‘burnt toast’ ice cream. I am a delicious contradiction that my own nervous system hasn’t quite figured out how to swallow. I am right, I am certain, I am Jewish-and yet, I am still responding to the bells. I am still waiting for the ghost of a holiday I no longer celebrate to tell me that the year is over.

The Grief of Asynchronicity

There is a specific kind of grief in this. It’s not that I want the old life back; I don’t. If I were offered a return ticket to my previous identity, I would burn it without a second thought. The grief comes from the lack of synchronization. I want to be a whole person, not a collection of warring reflexes. I want my hands to know what my head knows. I spent $77 on a new set of cookbooks, trying to force the scents of brisket and saffron into the floorboards of my apartment, hoping to overwrite the smell of ham and cloves that seems to linger in the drywall of my memory.

It’s a slow process. It’s like trying to repaint a house while you’re still living in it-you’re always getting wet paint on your sleeves, and the old color keeps bleeding through the primer.

The body moves at the speed of erosion. You cannot change the 207 bones in your body that have been conditioned by decades of specific movements.

When Logic Fails the Feel Test

I recently lost that argument at work, as I mentioned. It was about the fat-to-solids ratio in a vegan base. I had the data. I had the 47 test batches to prove it. But my boss just shook his head and said, ‘It doesn’t feel right, Ella.’ And he was right. It didn’t feel right. The numbers were perfect, the logic was sound, but the *feeling* was off.

Maybe the mistake is in trying to force the ‘feeling’ to catch up. Maybe the body isn’t a slow learner, but a faithful archivist. It’s keeping those memories of carols and prayers not because it wants to return to them, but because it’s the only way it knows how to measure time. My body remembers the 17th of December because that used to be a day of frantic preparation. Now, it’s just a Tuesday. But my body doesn’t know what to do with a ‘just Tuesday’ in December.

Grounding the Identity in Tactile Reality

I’ve started a new ritual to combat this, something small and physical. Every morning, I stand in my kitchen and I press my palms flat against the countertop. I feel the cold stone. I say my name-my new name. I do this 7 times. I am trying to ground the identity in the tactile. I am trying to tell my nervous system that this stone, this air, this woman is the reality. The rest is just a recording playing in a different room.

But then, a scent drifts by-maybe woodsmoke, or a specific brand of cinnamon tea-and I am 7 years old again, waiting for a miracle that I no longer believe in. And that’s okay. I’m learning to let the ghost sit at the table. I don’t have to feed it, but I don’t have to scream at it to leave either. It’s just a part of the architecture now. My brain understands that I have moved houses, but my feet still reach for the light switch in the old hallway. It doesn’t mean I’m in the wrong house. It just means I’ve lived a lot of lives, and they’re all still tucked away in the marrow of my bones, waiting for the temperature to drop.

The Necessary Void (Overrun)

In the ice cream lab, we have a term called ‘overrun.’ It’s the amount of air whipped into the ice cream. If you have too much air, the ice cream is cheap and fluffy. If you have too little, it’s a hard brick. You need exactly the right amount of space-the right amount of nothingness-to make the flavor carry. I think the ‘phantom’ memories are my overrun. They are the empty spaces that allow the new identity to have texture.

I remember sitting in a class on studyjudaism.net where we discussed the concept of a ‘Pintele Yid,’ that tiny spark of a Jewish soul.

I’ll probably never be fully ‘synced.’ There will always be a 7 millisecond delay between my heart and my head. I will always be the woman who knows the exact chemistry of a holiday she doesn’t celebrate, and the woman who is still learning the lyrics to the songs she now calls her own. I am a work in progress, a batch of flavor that is still setting in the freezer.
