Dear Reader,

Welcome to Yummy Lummy. Yummy Lummy is a blog for people who live alone and are keen to cook meals for one. If you’re part of a couple, I hope the recipes are adaptable for you, too.

I also share my opinions on topics others may (or may not) be interested in. With my recent change in diet (SAD→CSIRO TWD→LCHF), the blog’s emphasis is shifting to my opinion on some food and non-food-related topics. Comments are welcome, even if I disagree.

I cite most journal articles or books I’ve read and mentioned. You can see the citations at the bottom of the post.

You can skip the introduction and jump to the recipe if you don’t care to read my views.

Introduction

I hope you’ve had a good week.

My week was mostly enjoyable. I’m more mobile, and I’m able to exercise more. I attended a follow-up consultation with my surgeon, and he is delighted with my progress. He was complimentary of the physiotherapist I am attending.

Star Trek: The Next Generation  

Considering Kathleen’s generous gift of Patrick Stewart’s memoir, as I was listening, I developed an urge to rewatch TNG.

Watching "Encounter at Farpoint". I've been listening to "Making It So" by Patrick Stewart, and I experienced an urge to begin a Star Trek Next Generation rewatch.

Blood biomarker profiles and exceptional longevity: comparison of centenarians and non-centenarians in a 35-year follow-up of the Swedish AMORIS cohort (Murata et al., 2023)  

The authors hoped to better understand ageing by comparing a set of biomarkers.

The authors sought to:

1. describe and compare biomarker profiles at similar ages between 64 and 99 among individuals who become centenarians and shorter-lived peers,
2. investigate the association between specific biomarker values and the chance of reaching age 100 and
3. examine to what extent centenarians have homogenous biomarker profiles earlier in life.

Participants came from a study spanning 1985–1996 and were followed for up to 35 years.

The authors considered biomarkers of metabolism, inflammation, liver, renal, anaemia, and nutritional status.

One thousand two hundred and twenty-four participants (84.6% females) lived to their 100th birthday. There were 44,636 participants in the study.

Higher levels of total cholesterol and iron and lower levels of glucose, creatinine, uric acid, aspartate aminotransferase, gamma-glutamyl transferase, alkaline phosphatase, lactate dehydrogenase, and total iron-binding capacity were associated with reaching 100 years.

The authors suggest that genetic and possibly modifiable lifestyle factors reflected in these biomarker levels may affect longevity.

The paper describes an observational study and cannot make claims about causation.

Nevertheless, the author’s message for me is to maintain a low-carbohydrate, healthy fat, and no alcohol diet. Another key message from this paper is that longevity is not the be-all and end-all. I’d rather live well and die without lingering and suffering than live past 100 and be miserable.

Making It So: A Memoir by Sir Patrick Stewart

I’ve been enjoying Kathleen’s gift. So far, I’m up to Stewart’s period with the Royal Shakespeare Company. (Stewart, 2023)

It’s fascinating listening to Stewart’s adventures with the RSC. I was meant to read about half a dozen of Shakespeare’s works in high school. I never did. I was not a fan of English as a school subject. Of all the plays and books on the reading list, I only read one book. That was “The Chant of Jimmie Blacksmith”, written by Thomas Keneally and published in 1972. (Keneally, 1972)

I preferred reading non-fiction, especially biology or space travel. I barely passed humanities subject examinations in high school.

The total book will take more than 18 hours of listening. I’m about halfway through. I’ve been listening in the evenings.

Thanks, Kathleen, for this beautiful gift.

Today’s lunch

I bought some smoked New Zealand Pacific salmon for lunch and added it to scrambled eggs made with butter.

Recipe

The beef chuck is often regarded as a cheap and tough cut of meat. With beef and lamb becoming more expensive, cheaper cuts are becoming more desirable. The burden of the cost of living is especially true for people watching their pennies and keeping to a budget.

Equipment

• Slow cooker
• Air fryer
• Gas torch

Ingredients

• Beef chuck steaks — The two steaks (see photographs) cost $AUD12. I’ll get two meals from these steaks.
• Iodised cooking salt — 1 tablespoon.
• Tap water — ½ cup.
• Salted butter

Instructions

1. Place the meat, salt, and water into the cooking vessel.
2. Slowly cook for eight hours on low heat.
3. Remove the meat and place the beef on a tray and into the air fryer for 20 minutes at 160 °C (320 °F). An alternative to the air fryer is a frypan. I’d use a carbon steel or cast-iron frypan to sear the surfaces of the steak.
4. For the air fryer choice, once out of the oven, place a lump of salted butter on top of the steak and melt it with a gas torch.
5. Set aside some of the beef for dinner, put the rest into a container, and refrigerate. I will use the meat for lunches during the week.
6. Filter the cooking liquor and add it to my perpetual master stock.
7. Serve the beef with vegetables or eat them alone. If you’re following a carnivore diet, just the beef will be more than sufficient to satisfy your hunger. If you’re low-carbohydrate, healthy-fat eating, the meat and some plant-based “real foods” like avocado, leafy green leaves, olives, and tomatoes are a good combination. If you’re not concerned with carbohydrates, potato mash would go well with the beef. If you’re vegetarian or vegan, this beef won’t be suitable.
8. Always give thanks to the Lord.
9. Eat with whatever implements you prefer. Eating with your fingers is okay, in my opinion. Tonight, I used a steak knife and a fork.

Thoughts on the meal

Chuck steak has the beefy flavour of more expensive cuts like rump and scotch fillet (also known as ribeye in North America). The marbling gives the meat a rich, buttery flavour.

The melted and torched butter added a nutty flavour.

Slowly cooking the meat ensured tender muscle fibres, and the fat was nicely rendered.
