I never really understood St. Patrick’s Day. I am not Irish. I have zero, zippo Irish blood running in my veins. I’ve got Lithuanian and Iranian blood, you see, and when I moved the U.S. in the 70’s I had no understanding about things like Leprechauns or the Easter Bunny. Now, I’m a mom and I’m having fun with the many “holidays” celebrated in the U.S. and around the world.

Middle-Child has been scarred by these mischievous Leprechauns. When he was 4 and in preschool, the “Leprechauns” came into their room while the children played on the playground. The Leprechauns left a big mess! Of course, they also left candies and “gold,” but my young boy came home paranoid after this incident. My Princess was barely 2-years old and I asked Middle-Child to play quietly in his room while I put his sister down for her afternoon nap. When I came back to check on him, he was hiding under his sheets, terrified.

“What’s wrong, baby?” I asked frantically.

“Mommy, what if the Leprechauns come here and mess up my room? I don’t want to clean it up! They’re going to get me in trouble!” he cried to me.

I didn’t know if I should laugh or cry. So I hugged him tight and told him that the Leprechauns wouldn’t come to our house because we weren’t Irish. I reassured him that they only come to visit kids at school.

Just to be sure, he had me make a sign and posted it on our front door:

“Dear Leprechauns,
Please don’t come to our house.”

It took months before Middle-Child stopped talking about those naughty Leprechauns. When he started kindergarten, I asked his teacher if the Leprechauns were going to visit the classroom. Apparently there were several children scared of Leprechauns and the Leprechauns decided to skip Middle-Child’s classroom that year.

Whew! Crisis diverted.

Of course, now he is almost 8 years old and thinks Leprechauns are silly.

But he still doesn’t like them!

Which brings me to this lovely Baked Corned Beef. When I first made corned beef, I followed the directions on the package and slowly boiled it. It seemed good enough. I really didn’t know what I was doing, being a new wife. Boiling meat didn’t seem like a good idea, but it’s St. Patrick’s Day, right? Everyone’s doing it….

Then I baked my corned beef. OMG. Oh yeah, now this is a keeper. The corned beef flavor isn’t washed away like it is when you boil it, and the meat is super tender. The whole family ate it up and we had no leftovers! This is now my go-to recipe whenever we have a corned beef hankering!

Baked Corned Beef with Sweet-Mustard Crust Detail

I suppose this year, I should make a new sign for my front door.

Dear Leprechauns,

Please don’t mess up my house.
I have 3 kids and they do that pretty
well on their own. But, if you want
to leave a little gold, I will be more
than happy to accept your gift!

All the best,
