🥖 Castle & Cairn Banana Bread Recipe - Refined over 20 iterations

Castle & Cairn Banana Bread with Sour Cream
Yes it's a bit dark - that's the dark brown sugar!

We always seem to somehow end up with overripe bananas, so I find myself constantly needing to find a use for them. Banana break is by far the easiest final destination, and I'm never mad to have a slightly sweet breakfast option around.  As a wise man once said, "Banana Bread at work? Hell yeah!"

Banana Bread Recipe

Prep Time: 15 minutes
Bake Time: 60-70 minutes
Total Time: ~1 hour 25 minutes
Yield: 1 loaf (8-10 slices)

Ingredients 

  • 3 ripe bananas (medium, about 1 ¼ cups mashed; very ripe with brown spots works best)
  • 1 ½ cups all-purpose flour
  • 2 large eggs (room temperature)
  • ⅓ cup unsalted butter (melted - substitute with vegetable oil for a moister texture)
  • 1 tsp baking soda 

Spices/Seasoning:

  • ½ tsp salt - can skip if you use salted butter
  • 1 tsp ground cinnamon
  • ¼ tsp ground nutmeg
  • ¾ cup brown sugar
  • 1 tsp vanilla extract - who measures this anyway? 

Optional Ingredients:

  • ¼ cup sour cream or plain yogurt - HIGHLY RECOMMENDED - can sub in Greek Yogurt for more protein.
  • ½ cup chopped walnuts or pecans (for crunch, if you have them handy). Chocolate Chips also work well if you want a sweeter outcome. 

Directions

  1. Preheat oven to 350°F (175°C).
  2. Grease loaf pan generously.
  3. Mash Bananas - I typically just throw them in the stand mixer.
  4. Mix in ¾ cup brown sugar, ⅓ cup melted butter, 2 eggs, 1 tsp vanilla extract, and ¼ cup sour cream.
  5. Add 1 ½ cups flour, 1 tsp baking soda, ½ tsp salt, 1 tsp cinnamon, and ¼ tsp nutmeg - If you want, you can mix this in a bowl on the side first, but I just throw it into the mixer.
  6. Fold/mix in half the nuts or chocolate chips is using.
  7. Pour into loaf pan, smoothing top with spatula and sprinkling on the remaining nuts and a little bit of extra brown sugar if you're feeling frisky.
  8. Bake for 55-60 minutes. I would check it around 45min and cover with foil if the top is getting too brown. Assess with toothpick - should come out clean with a few moist crumbs. 
  9. Cool and serve - let sit for 10 minutes in the pan if happy with doneness otherwise try and get it out ASAP 

Other Tips/Discussion

For me, moisture is the key, so the addition of sour cream was a game changer. I prefer the density of the loaf made with butter over that of a version made with oil though. You can comfortably increase the cinnamon/nutmeg to about 200% of the values above before it becomes unbearable, but these are probably the best generalizable values. If the loaf is overly dense, you probably overmixed it. Similarly, if it sinks a bunch in the middle you may have had a little too much moisture, likely from some big banana energy. Reheats great in the microwave (about 15 seconds) and is perfect slathered with some more butter.

🥃📰 First Look: NEW Old Fitzgerald 7-Year Bottled-in-Bond Bourbon

In a TTB filing , Heaven Hill soft announces a new Old Fitzgerald edition whiskey: Old Fitzgerald Bottled-in-Bond 7-Year Bourbon. The Old Fitzgerald decanter line has long been a coveted edition, but low supply and high demand means that it is terribly hard to find, particularly for anything close to suggested retail price. Official press from the distiller has not yet occurred, but we have put together the following details.  About Old Fitzgerald From Heaven Hill's wheated mash bill (68% Corn, 20% Wheat, 12% Barley), the Old Fitzgerald decanter series is a Bottled-in-Bond offering released twice annually. This mash bill is also likely shared by the Larceny series of products, all aged in #3 char barrels.  Old Fitzgerald Decanter Series Old Fitzgerald 7-Year Bottled-in-Bond credit @Bourbonconky posted on X.com by  Bourb Your Enthusiasm The new product will have a seven year age statement, and per the bottled-in-bond act will consist of bourbon produced by Heaven Hill wit...

🥃Review #15 Costco's Kirkland Small Batch Bourbon

Costco's liquor store is a thing of beauty. While not every Kirkland edition is a hit, there are enough standouts on a fun per dollar ratio to always merit a look. Almost all of the house brands are less than $30, and I'm always excited to take a long shot when the new seasonal releases come around.  📚 Background: Distilled by Barton 1792 in Bardstown Kentucky, Kirkland Small Batch Kentucky Straight Bourbon Whiskey hits the shelves a few times a year. Mine was from batch 1124. The bottle presentation is supposed to evoke the same feel as other small batch whiskeys and there is a decorative purity seal that is reminiscent of the ever reliable bottled in bond green filigree, albeit in a meaningless red. Unlike its bonded brethren, this edition comes in under 100 proof and does not have any age statement. There's not a whole lot of additional information provided by Costco or the distiller, but we can reasonably assume that it shares a similar pedigree as the entry level 1792...

🥃Review #53: Costco's Kirkland 15YR Highland Single Malt Scotch - 2025

The 2025 release of Costco's Kirkland 15-year Highland Scotch hit shelves in late January and is a recurring installment on an annual cadence. The first pallet to hit my local store sold out almost immediately. Thankfully, we got two more shipments at one pallet each that hung around a bit longer and I was able to snag a bottle. Like in previous years, this Highland Scotch is finished in sherry casks. Alexander Murray & Co. is the bottler with MISA imports out of Texas bringing it to the States for consumption (Costco's standard sourcing pattern for Scotch). The bottle has a nice heft to it and there is an ensconced Alexander Murray Lion adding some nice texture to the front of the bottle. Steve Lipp, CEO of Alexander Murray, calls it "Perfect for after dinner drinking." All-in-all, this shows an attempt to elevate the product and presentation from the ubiquitous blends and non-age stated iterations you'll sometimes find under the Kirkland label.  Neither Alex...

🥃Review #30: Kirkland Bourbon Casked Rum XO

XO stands for "Extra Old" but how does this bottle of Bourbon Casked Rum from Costco's Kirkland Signature line measure up? 📚 Background: Finished in used Cognac barrels, this bottle is a product of Guatemala, imported for Costco by MISA IMPORTS out of Dallas Texas. MISA, named after the founder's children Michael and Sarah, started primarily as a sourcing partner for fine wines, but has since expanded operations into sourcing spirits. MISA's rum brand partners include 1731 , Autentico Nativo , and Navy Island. We would have to guess the maker if not for the back label which clearly identifies one Olivier Dumont, Master Blender. Mr. Dumont works for  Les Bienheureux , a French company growing at an alarming rate that has both a foothold in French Whisky and Costa Rican Rum. Les Bienheureux is the company behind "El Pasador De Oro " (roughly translated as "Gold Pin") which has two widely available iterations.  The XO version retails for $46.99 a...

🥃 Review #40: Kirkland Islay Single Malt Scotch Whisky (2024)

Like Costco's other Scotches, the Kirkland Signature Islay Single Malt is bottled for Alexander Murray and imported by MISA Imports after being distilled and aged in Scotland (TTB.gov plant registry TX-I-1277). The isle of Islay is one of the southern most islands in Scotland and is one of the five whisky regions ensconced in law. There are only nine active distilleries on the island, and the Islay style is typified by strong peat or smoky flavors. As a single malt, we know that the juice in this bottle comes entirely from one of those nine! All of the distilleries are significantly smaller than Glenlivet and many of the mainland producers. Taste testing has people split between Caol Illa, Bruichladdich (Port Charlotte), and Bunnahabhain as being the source. Caol Illa and Laphroig both have done deals for private brand scotch without rights to name the source distillery, but Laphroig does not match the flavor profile for this bottle. Realistically, Caol Illa is the most likely cand...
