My wife likes spreadable butter with olive oil and sea salt. When my local grocer started charging $5-6 per 13 oz container for her favorite brand, I decided to make my own with ingredients I like. After I perfected my recipe, we tried her favorite commercial brand again and it tasted flavorless. Total time to make 16 oz of spreadable butter is about 5 to 10 minutes prior to refrigerating. It's so easy and better than what you can buy.
Notes: if using unsalted butter, change sea salt to ½ tsp. Any butter will work, but Kerrygold gives the best flavor. The salt and sugar in the recipe are purely flavor enhancers and can be omitted. Do not over salt or the butter will liquify.
Do not use extra virgin olive oil because it overpowers the butter flavor. Only use extra light olive oil. Canola and vegetable oil also work but the final product has a little less flavor.
Cost with Kerrygold (Costco) and Bel O'lio Extra Light Olive Oil (also Costco) is about $4 per 16 oz of spreadable butter. Other butters and oils reduce the cost. Costco's Kirkland butter and the oil works well, too, and cuts the total cost to less than $2 per 16 oz of spreadable butter. I can't tell the difference, but my wife can. So, you know...HWHL.
Spreadable Butter with Sea Salt and Light Olive Oil
Ingredients
8 oz Kerrygold salted butter
8.5 oz extra light olive oil
¾ tsp white sugar
¼ tsp fine sea salt
Directions
Soften refrigerated butter in the microwave at power level 3 for 55 seconds (your microwave may differ). Do not melt! You can also just put the butter on the counter for 20 minutes to soften.
Add softened butter to the blender jar.
Add the oil. Hold the measuring cup over the blender and fill the cup until it just starts to spill over, then stop adding oil and dump the cup of oil in the blender.
Add the salt and sugar.
Blend at low setting for 50 secs to 1 minute. The final mixture should look smooth and creamy.
Pour and scrape with a spatula into two one-cup reuseable containers with covers and chill for several hours to overnight before use.
Keep refrigerated until ready to use. Do not leave on the counter as it will liquify.
